Repeat Problem 5.32, where now the signal is You can either sketch the plots by hand or use MATLAB for a more accurate plot. In order to examine the effects of aliasing in the time domain, plot x(t) for each of the sampling times for through 15 sec. In MATLAB, you can do this by defining your time vector with the time increment set to the desired sampling period. MATLAB then “reconstructs” the signal by connecting the sampled points with straight lines. (This procedure is known as a linear interpolation.) Compare your sampled/reconstructed signals with a signal that is more accurate, one that you create by using a very small sampling period (such
), by plotting them on the same graph.

Problem 5.32

Consider the signal with the amplitude spectrum shown in Figure P5.32. Let
 represent the sampled signal. Draw for the following cases:
