Abstract

The active comb filter without the use of inductors is very useful for removing harmonic noise such as power line interference in bio-medical signals. This paper presents an approach for the design of an active comb filter. A table composed of 62 bandpass filters is proposed, which can be used in the design of the presented active comb filter. Simulation results and performance tests are given to demonstrate the feasibility of the presented active comb filter.
