Unformatted text preview: ite the mean, autocorrelation function and the power spectral density of the random process representing noise source. b) Is the noise process wide-sense stationary? Justify your answer. c) Find the mean and average power of the voltage Y(t) across the capacitor. 2 d) Find the autocorrelation function of the process Y(t). e) Find the noise equivalent bandwidth for this RC circuit. 3 3. Nine resistors are sampled from a large box of resistors. The actual resistance values of these nine elements are: 3.9, 3.7, 3.7, 3.8, 3.5, 3.9, 4.0, 3.7, 4.2, all in the units of k. a) Find the sample mean. You must show all your work. b) Write out the formula for calculating the sample variance but do not evaluate it. c) Suppose that the true mean and true variance of the resistors are 4 k and 0.2 k2, respectively. Suppose now that 100 resistors are drawn at random from the box, and let denote the sample mean corresponding to the 100 samples. Use Chebychev's inequality to estimate the probability that the sampl...
