Robust Minimum Phase Finite Impulse Response Filter Design Algorithm Using Root Moments

摘要

In this paper a robust and versatile algorithm is proposed for minimum phase finite impulse response (FIR) design using root moments method. This algorithm has no constraints on magnitude response shape and runs relatively fast compared to several convenient algorithms implemented in MATLAB and SciPy. Presented experimental results show that proposed algorithm can be used as general-purpose transform to derive minimum phase FIR filter with magnitude response same as the original linear phase filter.
