Each of the following continuous-time signals is used as the input x_c(t) for an ideal C/D converter as shown in Figure with the sampling period T specified. In each case, find the resulting discrete-time signal x[n].

(a) x_c(t) = cos (2? (1000)t), ? ? ? ? ? ? ? ??T = (1/300) sec

(b) x_c(t) = sin (2? (1000)t). ? ? ? ? ? ? ? ? ?T = (1/1500) sec

(c) x_c(t) = sin (2? (1000)t) / (?t). ? ? ? ? T = (1/5000) sec
