. Write a program to smooth a random signal using averaging. First generate a noised sin wave (from 0 to 4"pi) (e.g, sin + 0.2 * rand). Then use three-pointer averaging method yn (X-1+Xn+ Xn+1)/3 to smooth the signal. Finally, plot the original and smoothed signals using subplots. Bonus design: try different averaging operator, for example, five-point averaging filter = (xn-2 + Xn-1 + Xn + Xn+1 + Xm2)/5, and weighted three-pointer filter yn-(Xn-1 + 2* Xn + yn Xn+1)/4, and compare the smoothing effects.
