Question

Let the signal x[n] shown in Figure P3.3.1. This signal is the input to three different LTI systems with the frequency responses H1(e^j?) through H3(e^j?) shown in Figure P3.3.2.

(a) Specify which kind of filter each system is, i.e., highpass, lowpass or bandpass.

(b) Find an expression for the output y[n] from each system and sketch that signal. Look at each H(e^j?) carefully as the vertical scale is not the same on all three plots.

(c) Do the outputs y[n] match what you would have predicted from part (a)?
