1.5 SINGLE-SIDEBAND MODULATSIOON e. SSB SSB on täiustatud versioon AM-ist, mille puhul kandva laine ja kahest ühe külgriba kaotamisega hoitakse kokku sagedusriba laiust ja saatja võimsust. 2. DIGITAALMODULATSIOONID Digitaalmodulatsiooni korral moduleeritakse pidevat kandevõnkumist digitaalsümboleid kandva signaaliga. Signaal oleneb sümbolitest, millel on piiratud arv võimalikke väärtusi. Binaarsel juhtumil on sümboli väärtus kas 0 või 1. 2.1 ASK e. AMPLITUDE SHIFT KEYING ASK korral muutub kandelaine amplituud vastavalt binaarse sisendsignaali väärtusele 0 või 1. Lihtsaim variant selleks on amplituudi sisse- ja väljalülitamine (on-off keying OOK), millega edastatakse Morse koodi. M-ASK kasutab suuremat arvu amplituudi väärtusi. Allpool on näidatud 4ASK, mis edastab ühel sammul vastavalt 2 bitti andmeid. 2.2 PHASE SHIFT KEYING e. PSK

From: ...name Subject: 'Business Today' event Dear Gloria, Thank for you letter informing me of the upcoming 'Business Today' event. I would like to confirm for you that I will attend. I am more than happy to be a speaker at the event and I would like to thank you for the great opportunity to do so. I do have a few questions regarding the speech that I will be giving. As to the topic I am fine making my own choice, but I would like to ask you if there are any specific topics or subjects that you would prefer that I talk about? I would also like to know how much time I will be alloted to speak? Will it be in a formal or an informal setting for the speech? I look forward to hearing from you regarding these details. I also would like to confirm that I will be able to attend the charity dinner as well. Thank you again for the opportunity and I look forward to seeing you at the conference. Much regards, ...name

they couldn't get away with it. I strongly believe in preventing problems before they happen. In much the same way as the Japanese prepare for earthquakes, countries with dry climates could have water catchment systems and reservoirs to defend against water shortage. I definitely think that countries should be self-sufficient in food and basic necessities. Don't you think it's better to stay single? Well, if you ask me, it all depends on your circumstances. Well, I think everybody should have the right to join a trade union. 4.2 Expressing a strong value ( It's / They're + value adjective) It's a nonsense to keep everybody at the same level regardless of their progress. ... their employers don't pay them a living wage. It's a scandal, because many pizza parlours, pubs and burger bars are really being subsidized by the Government.
Dear Mr Peterson, I am writing to ask more information about your place for training events, beacause I have to organize a youth seminar. I found your advertisement on the Internet. Firstly, I would like to know if the venue is open 20 Julay 2017? It will be suitable to have an evening time of 4:00 pm to 7:00 pm for the event. The main topic of the seminar is „Calm and Confident: Managing Stress and Tough Times". The number of participants is 30 (two teachers and 28 students). I know that you have a beautiful conference rooms, but what size are they? Also you said that you are offering a catering,but what kind of? We would need only snacks, how much it could cost? I look forward to hearing from you. Yours sincerely , Mari Mets

Morgan Holiday Home Address: My address: 6 February 2014 Beachside Holiday Home Dear Sir or Madam, My family is planning to spend a month in England and we wish to rent a holiday house. I have found the advertisement in the Internet and I am going to ask some questions. First of all I wonder if pets are allowed in the house of family booking? We have a dog and that would be really very difficult to leave him at home alone for two weeks. What about extra fee car parking? How much would it cost? Is there a fridge in the kitchen? I am also interested in price. All the rent costs 252 €? Including bed linen & towels? Or we have to take along our toiletries? And finally: What about internet access? Do you have it?

Leap of faith All of you, hopefully, will graduate from high school this year. It’s great. You don’t need to wake up at 6 or 7 AM. No more homeworks, teachers giving you bad grades, or days lasting up to 4 or 5 pm. Great. While it’s all party and stuff, people will tend to ask you one question all the time, as you start to finish your last year. I don’t know how many of you have suffered that pain already, but I have. People, friends and family more frequently, will ask you the following: ‘Hey. Soo… Who do you want to become in the future?’ First thing most of you will say is that: ‘Um, I’m not entirely sure, I’m yet to decide.’ The one who asks is confused: ‘It’s your last year of high school, you’re probably going to university next year or whatever, and you don’t know who you want to become?!?’ In our busy society where we live in, everything tends to move really fast.

Most schoolchildren won't tell you, often because they are afraid of reprisals. But certain symptoms should make you suspicious. These include unexplained reluctance to go to school; fearfulness or unusual anxiety; sleep disturbances and nightmares; vague physical complaints (headaches, stomachaches), especially on school days; or belongings that come home ripped or are missing altogether. If you suspect your child may be a victim, it's best not to ask the question outright. Dr. Sarah Shea, director of the Child Development Clinic at the IWK Health Centre in Halifax, suggests: "Ask your child indirectly how he or she is spending lunch hour; or what it's like walking to school, walking home or taking the school bus. Ask if there are any children at school who are bullies, without personalizing it. And when you meet with teachers, ask how they deal with conflict when it occurs. If you are certain your child is being bullied, let the

What is the best age to be? The question we all may ask ourselves time and time again. What is the best age to be? In my opinion there is not a best age and because of that is a question that will always be left unanswered. The life span approach emphasizes developmental change is throughout adulthood as well as childhood. As a 18 year old female I cannot really choose a specific age group that would be best in the life in every aspect, because I have not yet reached certain age periods of my life span development. All ages have great and bad things

65 Renard Square 12 October 2009 London SE6 WH9 Dear Sir or Madam Hello I am a student from Tallinn and I am looking for a summer job in the US. I was hoping that you could help me answer some of my questions. I have a lot of experience in construction work and also as a salesman, I have worked in several other jobs as well. I will send you my complementary CV later. First I would ask you what type of jobs do you have available in California? It doesn't have to be a construction or a salesman job, it could be something else too. About accommodation, how is it arranged, how much does it cost and how far away is it from the job location? I also wanted to ask you if the plane tickets are included and if they are not how much will they cost me. Another thing I am interested in is the work permit. What do I have to do to get it? Will I have to register somewhere?

And i was also wondering if the health insurance is included

Dear Mr President , I am writing in order to invite you to our class during the ,,Back to school" week. I think that your coming to my class would be really instructive and interesting for students. It would give everyone an opportunity to ask about your school times, life as a president and your position. I am sure that find out about your professional knowledge, perks and official duties helps us to understand your profession better. However, the lesson would be in English, so students can express them thoughts and ask questions in English. It would help us to evolve our communication in the formal way and it makes us richer by the experience. Visiting our school would be useful for you too. We could

whom they can rely on. Another suggestion is that the media should not promote drinking. Commercials are very effective with teenagers because commercials are very colourful and memorable. Also, when teenagers see some beautiful advertisement with lots of people who are having a party with drinks they want to be like them. What is more, these commercials teach them that a party is more fun with different alcoholic drinks. Finally, different clubs and pubs security guards should ask more effectively for documents to prove the age of the visitors. Too many teenagers are visiting clubs because they can get in easily. When security guards ask for documents then youngsters are not able to get any alcohol because shops are also closed by the time. All things considered, media should not promote drinking and people have to think more carefully before they take their alcohol bottle. When commercials are banned and people have
he always seems half naked. Jacob tells her that he has to carry his clothes around with him using a strap that is wrapped around his calf. Jacob decides to get to work and asks Bella where the intruder's scent was the strongest. When she replies her bedroom, his response is similar to what Edward's had been. But Jacob goes up and inspects the area like he was asked to. When Jacob returns he says that he caught the scent. As Bella washes the dishes, Jacob begins to ask her questions about her and Edward's relationship, centering on how she feels about him being a vampire and when she is planning on being changed. The anger and sadness of her answer, and the fact that it will be so soon after graduation, causes Jacob to clench down on a knife in his hand and cut himself badly. Bella witnesses his ability to heal quickly and it leaves her astonished. Jacob invites Bella to the reservation for a bonfire party, and Bella tells him she would ask if it was ok

You have always been very athletic and fast. You love running so maybe start playing football or even better, go join the track team at your school. I think the latter is more suitable for you. I'm sure you will make lots of friends who have similar hobbies with you. After all, you have always been very sociable and kind. About your home life. You told me that your dad is often on trips and when he gets home he is exhausted. Honestly, I doubt your father will ask you to do something with him, since he is always resting. I think you should take the initiative and ask him to the cinema. You could also take your sisters and your mother with you. Spending quality time like that with your family will certainly cheer everyone up. I'm going to have to cut my letter short, because I have to write some sort of a letter for tomorrow for my English lessons. Say hello to your sisters for me and write me as soon as you can! Best of luck, Egg.

You should: 1. Thank the caller. 2. Let the caller know you appreciate his/her business. 3. Provide assurance that any promises will be fulfilled. 4. Leave the caller with a positive feeling Some examples: "Thank you for calling. We appreciate your business " Tip: Let the caller hang up first This is simple courtesy, plus it gives the caller a final chance to add something. 5. And always remember: Smile as you dial! **What to do when you have to put customers on hold: 1. Ask them if you can put them on hold. 2. Tell them how long they will be on hold. 3. Assure them that you will be working for them while they are on hold 4. Wait for their response. 5. When you get back to them, thank them for holding. How to transfer customers on the telephone 1. Tell customers what you can do for them. Avoid saying, "I can't help you" or "This department does not handle that". By giving the name of the correct

bored with your job. Simple truth about getting over your sadness that may include in the quest to victory is, just ask yourself: ,,What sadness?" Keep calm and carry on! When you get overwhelmed by the failure, just take a break, deliberate it but whatever you do your trail of thoughts mustn't get affected by it. Still keeping focus on the problem will not only get it solved but it will keep you from causing new unnecessary problems. Now I ask, would you get wiser and improve your knowledge by learning from your mistakes, as to understand where have you gone wrong or would you be the one that thinks there's only one right choice and one answer to all dilemmas. At this very moment i'm writing this essay thinking will I get a polished grade or will my teacher give me an inadequate grade so I can improve my writing and debating skills for the better. So I would state, we find out more from our mistakes rather from our accomplishments.

1.1. What happened? Someone had killed mrs Shears dog named Wellington. 1.2. What do you think Christopher would want to do now? He would want to find a person who killed the dog and also get to know the reason. 1.3. How would you organise an investigation about the incident? I would talk to the owner and to the nabers, find out who would have a reason to kill the dog. 1.4. What would you do first? I would investigate the crime scene. 1.5. What questions could you ask? I would ask if anyone saw or hear something suspicious close to the time when the dog was killed and if anyone knows who would have a reason for killing this dog. 2. Read Extract 2 and answer the questions: 2.1. Write down what Christopher gets to know about the people in: Number 40 Number 44 Number 43 Number 39 The owners brother The lady answering the The guy who opened The lady who was
) Both her eyes were replaced in adulthood with glass replicas. 2. Learning was tough for Helen. Because of her deafness and blindness, no one could get through to her, and she could not communicate with others. Basic rules and lessons made no sense to her, and she was called a "wild child." Then, in 1886, her mom heard about the Perkins School for the Blind in Boston from Alexander Graham Bell, inventor of the telephone. Kate wrote to the head of the Perkins School to ask for a teacher for Helen and they sent their star student, Anne Sullivan. The day she arrived—March 3, 1887— Helen's life changed. 3. Anne Sullivan was born on April 14, 1866, in Agawam, Massachusetts. Her family had very little money and could not take care of her. When she was 10 years old she was sent to live in a home for poor people. Anne also had very poor vision. At the age of 14, she was sent to the Perkins School for the Blind to receive
