EE 23354 Data Communication HW3 25/12/2020 NAME (please print legibly): Your University ID Number: 1. (10 points) Consider the signal r(t) = 20 sinc(20+). (a) Calculate the F.T. of the signal z(t) (b) Determine the bandwidth of the signal r(t). (c) Determine the DC component in (t) (d) If r(t) is an input to an ideal low pass filter with cutoff frequency 107 rad/s, find the output of the filter. (e) Consider the signal y(t) = 2x(t) cos(100nt), Sketch and clearly label Y(w). Find the bandwidth and energy of the signal y(t).
