To find the zeros of the function it is necessary and sufficient to solve the equation : The zeros of the function will be the roots of this equation. Thus, the zeros of the function are at the point . Now, it would be very helpful as you add some of the other things you mentionedmore poles and zeros, all pass filterthen youre back in the business of making a filter design package. Think of poles as controlling a frequency-dependent feedback or resonancethe impulse response of a pole inside the unit circle decays, while one outside is like runaway feedback (think of a mic feeding back into a loudspeaker). But since I also calculated and display the coefficients, of course it could have been derived from the coefficients (as in Evaluating filter frequency response). While consider. Zeros absorb a particular frequency; when on the unit circle, they absorb the corresponding frequency completely. Poles and Zeros of Type-II Chebyshev Filter. Good idea, Matthijs.
