Title: | Minimum-Phase FIR Filter Design Using Real Cepstrum | Authors: | SOO-CHANG PEI Lin, Huei-Shan |
Keywords: | Minimum-phase finite-impulse response (FIR) filter; phase unwrapping; real cepstrum; root finding | Issue Date: | Oct-2006 | Journal Volume: | 53 | Journal Issue: | 10 | Start page/Pages: | 1113-1117 | Source: | IEEE Transactions on Circuits and Systems II: Express Briefs | Abstract: | The real cepstrum is used to design an arbitrary length minimum-phase finite-impulse response filter from a mixed-phase prototype. 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. |
