2.(10%) A periodic signal can be decomposed into harmonics with a fundamental frequency o and higher frequencies ko,kEZ. A simple system shown in Figure 2 is used to detect the period of the periodic signal. (a) (5%) How does this system work from time domain perspectives? (b) (5%) How does this system work from frequency domain perspectives? (Hint: model each tapped output; draw its pole-zero plot; etc.) Speech Input Tapped outputs Figure 2
