Abstract

Considering the incapability of updating operation at high sampling rate, a backward-deduction IIR notch filter was proposed, which can work at high working frequency. Then an IIR notch filter based on sliding window was further devised to efficiently decrease the signal loss and improve the acquisition capability with guarantee of the stability. The simulation results validate the correctness and efficiency of our proposed technology. It can be foreseen that this proposed IIR notch filter has good prospect in the practical system.
