1 establish the minimum sampling rate in hertz im not sure


1. Establish the minimum sampling rate in hertz. I'm not sure if my answers are correct.

a) x(t) = 4 cos2(100πt) My answer: 100 Hz

b) x(t) = 6 sinc(100πt) cos(200πt) My answer: 300 Hz

 

2. The Fourier transform of a continuous-time signal is

 X(f) = (1, |f|< 1

            0, else)

Derive x(t) and plot it.
