Question

g1(t) = cos(40*pi*t); g2(t) = cos(60*pi*t); g3(t) = cos(160*pi*t); a. Using a sampling period of 1.0 ms to simulate the continuous-time signal, in Matlab generate and plot the analog signal described in Problem 2 Part (a) over the interval 0 ? t ? 300ms, and overlay the plotted signal with the equivalents of its sampled versions. Denote the latter with different symbols (e.g., open circles, diamonds, etc). b. Repeat for g2 (t) and g3 (t) described in Problem 2 on separate graphs, and overlay each with their respective sampled counterparts. c. On the same graph, plot g1 (t) , g2 (t) and g3 (t) , and overlay them with discrete versions sampled at sampling frequencies that make the discrete signals identical.
