8. A signal is defined as xn] = cos(2 * T * 0.3 * n) for n = 1, 2,..., 15. Interpolate in time domain by a factor of 4 using zero padding in frequency domain. Plot all of the signals including every intermediate step in this procedure. 8. A signal is defined as xn] = cos(2 * T * 0.3 * n) for n = 1, 2,..., 15.
