1. Consider the continuous-time signal x₂ (t) = cos [ 27 (500)t] which is sampled at fs = 400 samples/sec. a) Find an expression for the resulting discrete-time signal x[n] = x₂ (nT), T: f. b) Find a discrete-time sinusoidal signal y[n] = cos(N₂n), -r≤ ≤, which yields the same sample values as x[n] in part a). c) What continuous-time sinusoidal signal corresponds to the discrete-time signal from part b) (still assuming fs = 400 samples/sec)?
