Matlab add white noise
Computer Experiment. Consider the linear system defined by Generate 1500 samples of a unit-variance, zero-mean, white-noise sequence xn, n = 0, 1, . . . , 1499 and filter them through the filter H to obtain the output sequence yn. Compute the sample cross-correlation ˆRyx(k) for k = 0, 1, . . . , 50 to obtain estimates of the impulse response hk.
