Q3 (a) Suppose Bartlett's and Welch's method is used to estimate the power spectrum of a signal x(n) consisting of N = (First Student id)(Last Student id)00 samples. (i) What is the minimum FFT block length (M) required to obtain a relative variance of 0.01 in your spectrum estimate, for Bartlett method and Welch method (using 50% overlap and hanning window)? (ii) Determine the frequency resolution (Af) of the spectrum estimate for Bartlett method and Welch method (using 50% overlap and hanning window).
