摘　　要：针对传统IIR陷波器在高采样速率时更新操作无法完成的问题,提出一种后推IIR陷波器实现方案,能够有效提高工作时钟;进一步设计基于滑窗算法的IIR陷波器实现方案,在保证系统稳定的前提下,有效降低信号损失,提高捕获性能。仿真结果表明本文所提IIR陷波器实现技术的有效性与较好的工程应用前景。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.
