Suppose that a continuous-time signal x(t)consists of several sinusoidal sections

(a) If the signal is sampled with a sampling frequency of fs = 8000 Hz, make a sketch of theideal spectrogram that corresponds to the signal definition.

(b) Make a sketch of the actual spectrogram that would be obtained with an FFT length of N = 256 and a Hann window length of L = 256. Make approximations in order to do the sketch without actually calculating the spectrogram in Matlab.
