Find the mean and Auto Correlation function of X (t) = Acos (cut + $) when w and are fixed. and A is a random variable with Normal density function of zero mean and Variance equal to two. Is x(#) a wide sense stationary random process?2.17 (a) Determine the overall amplitude response of the cascade connection shown in Figure P2.17 consisting of N identical stages, each with a time constant RC equal to to. (b) Show that as N approaches infinity, the amplitude response of the cascade connection approaches the Gaussian function exp (-f T' ), where for each value of N, the time constant To is selected so that 72 4T2 N R R R Buffer Buffer Buffer C C C amplifier amplifier amplifier Figure P2.17Question 3 1 pts Which of the following statements is FALSE about regression analysis?
