(a) A continuous-time signal x(t) = cosπ2p is sampled every T seconds, resulting in the discrete-time signal x[n] = x(nT) Determine whether the sampled signal is periodic for
(b) For those sampled signals in part (a) that are periodic, find the number of periods of x(t) in one period of x[n].
(c) For those sampled signals in part (a) that are periodic, find the number of samples in one period of x[n].
