摘要

A new approach for an active comb filter design is proposed to remove the difficult harmonic interference contaminating the biomedical signals. The filter consists of four narrow-band bandpass filters. The center frequency of each bandpass filters is just the unwanted frequency characterized by the harmonic interference. The circuit demonstrates the capability to eliminate the interference of 60, 180, 300, and 420Hz. The general 741 type operational amplifier has been used to realize the circuit presented. Triangular wave testing shows the effectiveness of harmonic interference cancellation.
