1. Write down python code by following steps A. Generate a discrete-time random signal x[n] having a sample length of 101 using np.random.randn(101) function. At this time the time interval is -50 to 50. B. Plot x[n]. C. Find energy and average power of x[n]. D. Find x[2n] and xEn], and Plot x[2n] and xEn]. E. When x[n] is decomposed into even signal xe[n] and xo[n], find xe[n] and x,[n], and plot xe[n] and x,[n]. 2. Generate a periodic signal xp[n] with T = 6. Repeat B through E of problem 1.
