Repeat problem 12 using the sliding discrete Fourier transform. Plot the magnitude of the SDFT as a function of time and frequency. Generate a discrete-time sequence of length 1024 samples consisting of say three distinct frequencies and unequal amplitudes. Use a sampling frequency of 5 kHz. Then perform the zoom FFT of the sequence, and plot the magnitude of the DFT. Compare this with the magnitude of the DFT of the original input sequence.
