Using MATLAB
(1) (a) Generate a time plot of fit)- 5cos(377t) -3sin(628t) for 4 seconds and sampled at 250 samples/sec. Label axes appropriately. (10 points) (b) Compute the DFT of f(t) to yield F(o). Plot the magnitude of F(o) vs. frequency in Hz. Label axes appropriately. (10 points) (c) Plot the phase of F(o) vs. frequency in Hz. Label axes appropriately. (10 points)
