The message signal m(t), whose spectrum is shown in Figure P-3.18, is passedthrough the system shown in that figure.

The bandpass filter has a bandwidth of 2W centered at fo, and the lowpass filter has a bandwidth of W. Plot the spectra of the signals x (t), yı (t), y2(t), y3 (t), and y4 (1).What are the bandwidths of these signals?
