Expert Solution
Step 1

Given the system a shown below:

Electrical Engineering homework question answer, step 1, image 1

xt(t)=sinc(t), fc=10 and the cut-off frequency of the low-pass filter is 1 Hz. We need to plot the signals xt(t) , yt(t), yd(t) and yf(t) and the magnitudes and phases of their CTFT's.
