Given An Energy Signal Where T 0 Use Your Previous Matlab Code To Plot Its Energ

1.    Given an energy signal , where T=0.1 ms.

a.    Use your previous Matlab code to plot its energy spectrum density, which is the absolute square of its Fourier transformation. From the energy spectrum density, figure out its 3dB bandwidth.

b.    For an FM signal with modulation index of 0.5, calculate the frequency deviation and the corresponding .

c.     Pick up carrier frequency equals to 5 times of the frequency deviation, plot the time domain FM waveform.

d.    Plot the spectrum of FM signal.

here is the previous code
