2 of3 5 Discrete Fourier Transform In class, we study the how to compute the Fourier transform for continuous signals f(t) as F(w)-f(t)e dt. For discrete signals, a similar computation can be performed to compute the discrete Fourier transform. To compute the discrete Fourier Transform in MATLAB, fft is the command to use. Task 3: a) Plot the magnitude of the Fourier transform of each of the first two rows of the matri:x trainAudiorecords. Comment on any differences/similarities you see in the transforms b) Since we have a real signal, the magnitude of the Fourier transform should be an even function. However, the output given by fft starts at 0 (not centered at 0),.e., t shows
