The message signal m(t), whose spectrum M(f) is shown below, is passed through the system shown in that

The message signal m(t), whose spectrum M(f) is shown below, is passed through the system shown in that figure. m(t) y(t) = x(t) Square Law Bandpass YEEKE Filter M (f) os2 fot x(t) Device -W cos2nfot W Y (t) Y3 (t) Lowpass Filter Y4 (t) 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), y(t), Y(t), y(t), y(t). What are the bandwidths of these signals? Act
