摘要：
A method for designing IIR complex wavelet filters based on complex allpass filters, that are maximally flat at omega = 0, is presented. This allpass filter is obtained from complex allpole filter with a desired flatness at omega = 0. The parameters of the complex allpass filter design are the order of the filter N, the degree of flatness K, and the phase phi(0) at omega = 0. The real and imaginary part of the filter coefficients are computed from the proposed iterative equations.
