There is no need to start with the odd-length equiripple linear-phase filter first. Neither the phase-unwrapping nor root-finding procedure is needed. Only two fast Fourier transforms and a recursive procedure are required to find the filter's impulse response from its real cepstrum. The resulting filter's magnitude response is exactly the same as the original one even when the filter is of very high order.313205 bytesapplication/pdfMinimum-phase finite-impulse response (FIR) filter; phase unwrapping; real cepstrum; root findingjournal article10.1109/TCSII.2006.8821932-s2.0-33750601021WOS:000241438800025
