Prob. 7.9
Let x(t)=cos 2pt.
Suppose this signal is sampled at a frequency of ws
and then reconstructed using an ideal low-pass filter with cut-off frequency
at ws/2.
Determine the reconstructed signal for the following ws.
Illustrate what is happening in both the frequency domain by drawing original
and sampled signal spectrum, and the sampling and reconstruction process
in the time domain.
