Design a (real) digital notch filter that rejects 5000-Hz content completely and sharply recovers on either side of 5000 Hz to a gain of unity. The highest frequency to be processed is 20 kHz (f_max
= 20000 Hz). Provide a canonic realization of the filter, and determine the filter’s magnitude response.
