Abstract
Interpolated finite impulse response (IFIR) filters drastically improve the computational efficiency of low-pass finite impulse response (FIR) filters designed using the traditional Parks-McClellan design method. This article presents a trick to further improve the computational efficiency of traditional IFIR filters.
