2. * Consider the following signal f(t) = 5 cos(5mt) + 6 sin(25mt). (a) What is the highest angular frequency present in the signal? What is the highest numerical frequency present in the signal? (b) What is the Nyquist rate of the signal? Did you use the angular or the numerical frequency? (c) If you sample this signal with sampling period T, which values of T satisfy the Nyquist require- ment? Choose and fix one such T. (d) After sampling, you pass the sampled signal through a low-pass filter that cuts off the frequency at Mo. What is the range of the cutoff frequency, Mo of the filter to avoid aliasing and avoid signal loss? 2. * Consider the following signal f(t) = 5 cos(5mt) + 6 sin(25mt).
