Letw[n] denote the linear convolution of x[n] and y[n]. Let g[n] denote the 40-point circular convolution of x[n] and y[n]:

(a) Determine the values of n for which w[n] can be nonzero.

(b) Determine the values of n for which w[n] can be obtained from g[n]. Explicitly specify

at what index values n in g[n] these values of w[n] appear.
