Question: a continuous time signal given as xt cos48 pi...

Question details

PROBLEM 10.1 A continuous time signal, given as x(t) cos(48Tt +4), is being sampled with an ideal C-to-D converter at a sampling rate of 42 samples/s, resulting in a discrete time sequence x[n] (a) Find the period No of xInl, (b) Sketch a stem plot of two periods of xInl, 0 sns2No 1 mark all relevant values properly, (c) Sketch a stem plot of two periods of x[10-n], 6sns2No +5 mar all relevant values properly, (d) Express mathematically yInExln] +x[10-n].
