Microcontroller homework for week 04 1. SNR - Ratio of RMS signal to RMS SINAD - Ratio of the RMS signal amplitude to the mean value of the root-sum-square (RSS) ENOB - The effective number-of-bits and relates to SINAD THD - Ratio of the rms value of the fundamental signal to the mean value of the RSS of its harmonics. SFDR - Ratio of the RMS value of the signal to the RMS value of the worst spurious signal. Channels related to the inputs of the ADC can either be multiplexed or individually selected. Linearity relates to how a ADC follows a linear function. All ADCs are to a certain extend non-linearity. Temperature is measurement, which in optimal state for ADC-s, lets them function correctly. Power dissipation refers to the amount power dissipated when the ADC is operating. 2. The output code is 001111012 and the voltage of the LSB is 0,0195V 3
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)

sufficient for the systems, machines, and equipment, and be sure to provide the systems, machines, and equipment with double safety mechanisms. This manual provides information for programming and operating the Unit. Be sure to read this manual before attempting to use the Unit and keep this manual close at hand for reference during operation. ! WARNING It is extremely important that a PC and all PC Units be used for the specified purpose and under the specified conditions, especially in applications that can directly or indirectly affect human life. You must consult with your OMRON representative before applying a PC System to the above-mentioned applications. 3 Safety Precautions
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:

We can store and retrieve data much more efficiently. We can communicate in a flash. But still, at the basic level, we must be well grounded -- we must possess common sense, civil manners, frank discussion skills, reasoning abilities, and moral fiber. It is possible to be a technological genius, say a computer nerd, without social skills or civil conscience. I'd rather have as a neighbor an illiterate janitor with an easy-going, friendly disposition. Hence, I value what we might call character more than specialist knowledge from an antisocial person. God knows we want everyone to be a well-mannered genius. But humans are not cut out to be happy like pigs in a pen. We instead have insatiable brains, with mental appetites. So our goal is to balance the brainwork with hearts and smiles. "Facts served with sauce." Where does common sense fit on? Is it teachable? To a degree, what we mean by common sense is simply learned experience
CODEBREAKING is the most important form of secret intelligence in the world today. It produces much more and much more trustworthy information than spies, and this intelligence exerts great influence upon the policies of governments. Yet it has never had a chronicler. It badly needs one. It has been estimated that cryptanalysis saved a year of war in the Pacific, yet the histories give it but passing mention. Churchill's great history of World War II has been cleaned of every single reference to Allied communications intelligence except one (and that based on the American Pearl Harbor investigation), although Britain thought it vital enough to assign 30,000 people to the work. The intelligence history of World War II has never been written. All this gives a distorted view of why things happened. Furthermore, cryptology itself can benefit, like other spheres of human endeavor, from knowing its major trends, its great men, its errors made and lessons learned.

HatYai, Songkhla 90112 E-mail: [email protected] Draft: 14th January 2003, #2 Abstract This article looks at the advantages and disadvantages of using Java and Java 3D for games programming. It assumes the reader is familiar with Java, but presents short overviews of gaming, the low-level APIs OpenGL and DirectX, and Java 3D. No programming examples are included here, although links to online code are supplied. 1. Background to Gaming Giving a definition for `computer game' is problematic, due to the wide range of game types. For example, the ArcadePod site (http://www.arcadePod.com) divides its hundreds of Java games into more than ten categories: 3D games, multiplayer, action, classic, indoor sports, board, outdoor sports, card, mind, casino, educational, and the useful `miscellaneous' catch-all. This makes it difficult to pin down the typical
In this example, the form of the argument was obtained by the substitution of letters (A, B, C) in the place of the terms (groups of things). This process is called a formalism. Missing Premises The determination of the form of an argument requires caution. It is important to ensure that all premises are explicitly stated. Sometimes, an argument needs the addition of an implicit premises to get the complete form. This figure is a square. Therefore, this figure has four sides. There is a missing premise: All squares have four sides. So the full argument is now apparent: All squares have four sides. This figure is a square. Therefore, this figure has four sides. Validity/invalidity of forms Let us consider the following form: All A are B All C are A Therefore, All C are B. When the premises are true, the conclusion is necessarily true. This is a valid form. Let us consider the following form:
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,
greenhouse gases. 3.2 Why Don't We Use More Renewable Energy? In the past, renewable energy has generally been more expensive to use than fossil fuels. Plus, renewable resources are often located remote areas and it is expensive to build powerlines to the cities where they are needed. The use of renewable sources is also limited by the fact that they are not always available (for example, cloudy days reduce solar energy, calm days mean no wind blows to drive wind turbines, droughts reduce water availability to produce hydroelectricity). The production and use of renewable fuels has grown more quickly in recent years due to higher prices for oil and natural gas, and a number of State and Federal Government incentives, including the Energy Policy Acts of 2002 and 2005. The use of renewable fuels is expected to continue to grow over the next 30 years, although we will still rely on
Peer evaluation of writing helps learners to become aware of an audience other then the teacher. The teacher can also respond at this stage by commenting on the content and the organisation of ideas, without yet giving a grade or correcting details of grammar and spelling. Reviewing When writing a final draft, students should be encouraged to check the details of grammar and spelling. (The teacher can use codes to help students correct their own writing and learn from their mistakes).

report, some of the specifics (section headings, length, and format) may be determined by your project client. Before You Begin Some basics that you need to understand before starting to write the report. Definition: A design report documents the solution to a unique problem. Purpose: To communicate the solution to a problem. Audience: Anyone who has to implement your design, understand your design, or reference your design to solve their own problem. Typically, this is the project client. While the client may be familiar with the project, the report is still written as though the client is new to the project because that is the best way to tell the whole story. A design report is different than a lab report that you might be familiar with. A lab report describes an experiment and its conclusions and has four main parts: Introduction, Methods, Results and Discussion.

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.

Sick: Good. 18. Affixation In linguistics, the process of adding a morpheme* (or affix) to a word to create either (a) a different form of that word (e.g., bird → birds), or (b) a new word with a different meaning (bird → birder). The two primary kinds of affixation are prefixation (the addition of a prefix) and suffixation (the addition of a suffix). Clusters of affixes can be used to form complex words. “An affix is a bound morph that (1) is not a root and (2) is a constituent of a word rather than of a phrase or sentence”. “For example, in the words misfortunes and premeditated, the roots are clearly fortune and medit-, because these morphs make the most concrete and distinctive contributions to the meanings of these words; furthermore, fortune is free, as most English roots are. (The root of premeditated is medit- , not meditate, because –ate is a verb-forming affix that occurs also in generate, vibrate, and many other words.)”
