Consider a continuous-time sinusoid x(t) = 3 cos(100nt + ) a) Suppose the signal is samples at F, = 200Hz. What is the obtained discrete-time sinusoid x[n] = A cos(wn +") ? b) For F, = 200Hz, determine Nyquist frequency range (NFR) for x(t) c) For F, = 200Hz, determine a general expression for all the aliases of x(t) d) Starting from x[n], what is the equivalent rads-1 frequency that one gets if F, = 200Hz. Does it lie in NFR ? e) Repeat parts a)-d) for F, = 75Hz
