Week 4 homework. Question 1: 1. SNR – Ratio of root mean square signal to root mean square. 2. SINAD – Ratio of the RMS signal amplitude to the mean of value of the root sum square. 3. ENOB – The effective number of bits and relates to SINAD. 4. THD – Ratio of the rms value of the fundamental signal to the mean value of RSS of its harmonics. 5. SFDR – Ratio of the RMS value of the signal to the RMS value of the worst spurious signal. 6. Channels – multiple analog signal inputs to the ADC that can be individually selected or selected through a multiplexor. 7. Linearity – Describes how an ADC conveter follows a linear function. 8. Operating temperature – A temperature at which the ADC functions optimally, usually given by the manufacturer. 9. Power dissipation – The proportion of power dissipated (through heat) when the ADC is working. Question 2: An 8 bit ADC has a reference voltage of 5V. What is the digital output code word for an input of 1.2V
Question 1 (in wiki and in terminologies) 1. SNR is a calculated value that represents the ratio of root- mean-square (rms ) signal to rms noise. 2. SINAD stands for Signal-to-noise and distortion ratio. It is a measure of the quality of a signal from a communications device, often defined as: where is the average power of the signal, noise and distortion components. SINAD is usually expressed in dB. For examples to calculate the ratio of 1 kW (one kilowatt, or 1000 watts) to 1 W in decibels, use the formula 3. ENOB is the effective number-of-bits related to SINAD and the quality of a digitized signal. The 6.02 term in the divisor converts decibels (a log10) to bits (a log2) The 1.76 term comes from quantization error in an ideal ADC 4. THD - Total harmonic distortion is the ratio of the root-mean-square (rms)

An Anode has positive potential and therefore collects electrons in the device. Cathode has negative potential and therefore emits electrons to anode. The symbol looks like an arrow that ponts from the anode to the cathode, and reminds that conventional current flows easily from the p side(anode) to the n side(cathode). BIASING. Forward biasing. If the current in a diode is too large, excessive heat will destroy the device. Even approaching the burnout current value without reaching it can shorten its life. Therefore manufacturer's data sheet specifies the maximum forward current, that diode can withstand. This average current IF is the rate a diode can handle up to the forward direction when used as a rectifier. Another entry of interest in the data sheet is the forward voltade drop UF(max) when the maximum forward current occurs. An usual diode has this value 0.7-2.0V. Diode conducts easily when forward biased. Reverse biasing

called make-before-break. The interval, during which the two connections are used in parallel, may be brief or substantial. For this reason the soft handover is perceived by network engineers as a state of the call, rather than a brief event. Soft handovers may involve using connections to more than two cells: connections to three, four or more cells can be maintained by one phone at the same time. When a call is in a state of soft handover, the signal of the best of all used channels can be used for the call at a given moment or all the signals can be combined to produce a clearer copy of the signal. The latter is more advantageous, and when such combining is performed both in the downlink (forward link) and the uplink (reverse link) the handover is termed as softer. Softer handovers are possible when the cells involved in the handovers have a single cell site. (umts – 3g, gsm – 2g) UMTS-is:

Achieving cost reduction or profit improvement at the expense of their supply chain partners does not make companies more competitive. Transferring cost upstream or downstream leads to "logistics myopia" as all costs ultimately will make way to the final market place to be reflected in the price paid by the end user. Therefore, the leading edge companies seek to make the supply chain as a hole more competitive through the value it adds and the cost it reduces overall. Thus today the real competition is not the companies against the companies but rather supply chain against supply chain. DEFINITIONS Supply Chain Management (SCM) is the process of planning, implementing, and controlling the operations of the supply chain with the purpose to satisfy customer requirements as efficiently as possible.

Iseloomustab kvaliteeti. Antud valmis alati kordades! S ( signaal ) SNR= N ( müra ) SNR [ dB ] =10 ∙ log ( NS ) Additive white Gaussian noise (AWGN) is a basic noise model used in Information theory to mimic the effect of many random processes that occur in nature. The modifiers denote specific characteristics: Additive because it is added to any noise that might be intrinsic to the information system. White refers to the idea that it has uniform power across the frequency band for the information system. It is an analogy to the color white which has uniform emissions at all frequencies in the visible spectrum. Gaussian because it has a normal distribution in the time domain with an average time domain value of zero. 8.

becomes polyalphabetic. A simple form of polyalphabetic substitution would be to add another cipher alphabet under the one given above and then to use the two in rotation, the first alphabet for the first plaintext letter, the second for the second, the first again for the third plaintext letter, the second for the fourth, and so on. Modern cipher machines produce polyalphabetic ciphers that employ millions of cipher alphabets. Among the systems of substitution, code is distinguished from cipher. A code consists of thousands of words, phrases, letters, and syllables with the codewords or code-numbers (or, more generally, the codegroups) that replace these plaintext elements. plaintext codeword emplacing DVAP employ DVBO en- DVCN enable DVDM enabled DVEL enabled to DVFK This means, of course, that DVDM replaces enable.

Uses only two symbols: 0 and 1. The choice of using binary numbers is dictated by cost and reliability. Binary circuits: Electronic circuits are cheapest and most reliable if they only assume two states or conditions. These binary circuits have only two states, ON or OFF. Standardized means of storing these codes: ASCII (American Standard Code for Information Interchange) EBCDIC (Extended Binary Coded Decimal Interchange Code) UNICODE (Extended ASCII) Each pixel contains a value representing some shade of gray. The more shades of gray possible, the more memory will be needed. Instructions: Must be stored within the computer before use. Must be stored in binary form.

In this direction, Georgian Govern- ment made several important steps: Tax -The administration of tax and customs systems has been simplified. The number and rates of taxes have been significantly reduced making it easier for local and foreign businesses to do business. Currently, there are only 6 taxes and no capital gains, inheritance, wealth, property transfer; social, branch remittance or any other taxes are in place in Georgia. The coming into effect of a new comprehensive Tax Code (including customs legislation) on January 1, 2011 con- stitutes a further milestone in the development of tax legislation. Licenses and permits - Georgia has dramatically reduced licensing and permitting requirements to ease constraints on business. The total number of licenses and permits was cut by 84% in re- forms that eliminated 756 licenses and permits and streamlined procedures. Currently, licenses

In typical projects, the general contractor takes responsibility for procuring the steel, arranging for fabrication, and ultimately building the structure. The contractor first selects the shop drawing detailer and the steel fabricator. The detailer develops preliminary shop drawings, used for ordering steel from the mill for delivery to the fabricator. Thus the prime contractor assumes the risk for availability and delivery of steel to meet the contract schedule. This highly linear process can add six to eight weeks to the project schedule for a complex structure (Whited & Gatti, 2007). During construction, problems tend to amplify when the wrong steel arrives at the wrong time on the jobsite due to poor tracking by the fabricator. Moreover, it can be very difficult to explain complex erection schedules to the steel crew based on 2D drawings. Additionally, explaining field discrepancies to the project managers and detailers can be
This is the musical chronicle of an epoch already lived. Naturally, one person cannot grasp it totally with all its multiple manifestations: it seems impossible. Therefore we have to have certain reservations when evaluating the works of composers who are still writing. There is no temporal distance between music and the listener. The spirituality and pithiness of music opening up in the course of time pronounce the last word on either the value or worthlessness of any musical composition. I am writing about Estonian symphonists and symphonism. What do I mean by this term? For example, one can speak of the symphonism of Eduard Tubin, Artur Kapp and Arvo Pärt. In its best and exact sense symphonism means the creation of a sublime philosophical idea in music in an intense extensive and developing form. Symphonism is a way of thinking through the medium of music and therefore perhaps the most prefect way in its singularity
Christopher Vogler Under Fire, Volcano, Anna and the King, Fight Club, and The Thin Red Line. M y concepts o f s t o r y t e l l i n g , shaped by the patterns of mythology and the thinking of Joseph Campbell and Carl Jung, were now being tested not only on animated features but on big-budget, live-action movies for adult audiences. T h e office atmosphere of Fox 2 0 0 0 was a fascinating place to study the ways of power. In the past I h a d been aware o f places like it, but as a story analyst I h a d not been inside those meeting rooms where the decisions were taken about the writers, the stories, and the movies made from them. Power flows in those rooms like hot lava, and until I worked at Fox 2 0 0 0 I had only heard it rumbling. Now I was standing hip deep in it. It was the most adult environment I had ever been in, run on unspoken but rigorous principles of personal responsibility
the master program of your subconscious computer, determining everything you think, say, feel, and do. For this reason, all change in your outer life begins with a change in your self-concept, with a change in the way you think and feel about yourself and your world. The child is born with no self-concept at all. Every idea, opin- ion, feeling, attitude, or value you have as an adult you learned from childhood. Everything you are today is the result of an idea or im- pression you took in and accepted as true. When you believe some- thing to be true, it becomes true for you, whatever the fact may be. “You are not what you think you are, but what you think, you are.” ■ FIRST IMPRESSIONS ARE LASTING If you were raised by parents who continually told you what a good
Philosophy of Language Philosophy of Language: a Contemporary Introduction introduces the student to the main issues and theories in twentieth and twenty-first-century phi- losophy of language, focusing specifically on linguistic phenomena. Topics are structured in four parts in the book. Part I, Reference and Referring, includes topics such as Russell's Theory of Descriptions, Donnellan's distinction, problems of anaphora, the description theory of proper names, Searle's cluster theory, and the causalhistorical theory. Part II, Theories of Meaning, surveys the competing theories of linguistic mean- ing and compares their various advantages and liabilities. Part III, Pragmatics and Speech Acts, introduces the basic concepts of linguistic pragmatics, includes a detailed discussion of the problem of indirect force and surveys approaches to metaphor. Part IV, new to this edition, examines the four theories of metaphor. Features of Philosophy of Language include: · new c

So you break the window of the pharmacy and take the medicine and save the man. International example: you're in a boat on international waters, boat starts sinking of something is wrong (military ship) and you need help so you enter to the territorial waters of another country without permission to save yourself and your boat. Only if you have no alternatives. Life of a person is considered as absolute value. You cannot excuse killing of one person for the saving of three persons, e.g. to get organs from the dead and give them to the living. In certain situations it can be acceptable. Countermeasures you violate certain obligations in response of the violations of your partner. It's not a universal measure. You can use it if it's not directly prohibited by international law. In some areas nowadays it's prohibited, e.g. law of war. Earlier it was
