SOLVED: Problem 3 Let x(t) be a signal with Nyquist rate ωo. Nyquist rate is the frequency which, under the sampling theorem, must be exceeded by the sampling frequency. Determine the Nyquist rate for each of the following signals: a) x(t) + x(t-3) b) x(3t+2) dx(t) c) dt d) x(t) cos(3t) e) x^2(t) f) x(t) * x(t)
