Problem 18 Noise: The formula for Johnson-Nyquist noise is v = V4KTRB. These values are given: • k = 1.380648522 10-23 K T = 295 K (standard room temperature) R = 5 MN B (bandwidth) = 20MHZ Assume that you have a 12 bit ADC and that the input range of the ADC is 1 V. Calculate the noise voltage due to J-N for this circuit, and then compare this voltage to sensitivity of ADC. That is, how many ADC steps do you expect the measurement to fluctuate due to J-N noise. You should round your answer. Enter the integer number of steps.

Problem 2 Consider sampling input cosine functions, with a sample rate of 100Hz. (a) What is Nyquist Frequency in Hz? (b) What is the period associated with Nyquist Frequency? (c) During one period, how many samples are taken at the Nyquist frequency signal? (d) Give the values at the sample times when you start sampling at time zero. (e) Give the values at the sample times if you are sampling a sine function that is oscillating at Nyquist frequency. (f) Give the values at the sample times if you are sampling a cos (wyt - at times t = kT where T is the sample time interval for Nyquist frequency (the means that the cosine is shifted 45 degrees back in time compared to the original cosine, i.e. a phase delay from input to output). (g) We commented in class that if a cosine is sampled such that there are 4 or more samples in each period, then the control action based on the sampled values might be able to make some effective corrective action. If Nyquist frequency is 100Hz, what sample…
