Question 1: a) For any linear phase filter, prove that if zo is a zero, then so must zobe. Hint: Using the properties of the z-transform, write h[n] = Eh[N - n) in the z-domain, and substitute 2 = 20. b) For any Type III or Type IV filter, prove that z = 1 is a zero. c) For any Type II filter, prove that z = -1 is a zero. d) In light of the above, find the zeros...

3.2 Simple Bandpass Filter Design The L-point averaging filter is a lowpass filter. Its passband width is controlled by L, being inversely proportional to L. In fact, you can use the GUI altidemo to view the frequency response for different averagers and measure the passband widths. It is also possible to create a filter whose passband is centered around some frequency other than zero. One simple way to do this is to define the impulse response of an L-point FIR...
