Assume the cutoff frequency is equal to 1, the poles of the filter are the zeros of the gains denominator The poles of the gain of type II filter are the opposite of the poles of the type I Chebyshev filter. It is quite difficult to qualitatively analyze the Laplace transform (Section 11.1) and Z-transform, since mappings of their magnitude and phase or real part and imaginary part result in multiple mappings of 2-dimensional surfaces in 3-dimensional space.For this reason, it is very common to examine a plot of a transfer function&x27;s poles and. If the poles or zeros are not repeated, then the function is said to be having simple poles or simple zeros.
