中文摘要	A linear phase comb filter design method was developed which combines a high pass filter and a fractional delay filter for sample rates that are not a multiple of the notch frequency. A polyphase filter structure is applied instead of a direct structure to the finite impulse response (FIR) comb filter based on the fractional delay to reduce its design complexity. These filters have a linear phase response in the pass band and generally have high pass filter notch performance at its notch frequencies. Promising result has been achieved in applications to electrocardiogram (ECG) signals contaminated by baseline wandering and power line interference and its harmonic components.
