3. (a) What is noise, noise voltage and noise power due to a resistor and why understanding and controlling of noise is critical in telecom signal transmission? Estimate the noise voltage and noise power generated by a 1 MO resistor at RT 40 °C if BW is 18 MHz. Is this noise significant? [Hint: en V 4kT (Bw)R, Pn kT (BW), k 1.38x102 [10] (b) Define channel capacity C and explain how it is affected by the S/N ratio. The...

Q1 Marks: 40 A digital communication system has 96 analog telephone signals, each band limited to 4 kHz. The telephone signals are converted to digital binary data using Pulse Code Modulator (PCM) system, which use a uniform quantiser followed by an 8-bit encoder. The system uses two bits for synchronization. The digital binary data are then time-division multiplexed and transmitted over a single communication channel. Analyse the communication system by considering the following principles: (i) Determine the number of quantization...

A. Draw yorphs showing the effect on action potentials in a cell following effective doses of each of the listed neurotoxins. Assume that the cell is normally brought to threshold by an electrical stimulus applied to it, so that any abnormality is due to the toxin. Precise values for voltage and duration are not important, just a general trend in how the action potential may be...

Use a behavioral Verilog model to design a 3-bit fault tolerant up-down counter. For each flip-flop (FF) include asynchronous reset and preset signals. Refer to Example 4.3 on page 160 for an example of a single FF with both reset and preset signals as well as with an enable signal. For this project, you don't need to use FFs with enables. You don't also need not-q (nq) in this assignment. Use active-high signals for reset and present signals. The example...

Give two examples of fiscal stimuli (4pts each=8 pts) and explain why/when a government would use these (4pts). Explain how corporate tax cuts could be an engine for economic growth (5 pts). According to the RWM article, explain 2 ways the GOP Tax plan could increase income inequality (4 pts each=8pts).[hints: using an example to explain the need for fiscal stimuli and what it is may be helpful in answering this question].

For this question, you are to use a graph to illustrate the change(s) and then explain the situation in one or two sentences. You may have to go back to earlier material to find some of the answers. You may assume that the economy is in a long-run macroeconomic equilibrium at the beginning of each part. Draw the aggregate demand and aggregate supply model. Illustrate long-run macroeconomic equilibrium. (2.0 marks) There is a decrease in the money wages paid to...
