摘要
提出了一种利用自适应IIR陷波器抑制声反馈的方法。该方法根据Sign-LMS最小均方算法调整陷波系数,使用的DSP是16位定点处理器TMS320C50。在不同条件下的实验结果表明,该方法能快速、有效地抑制声反馈。
An adaptive acoustic feedback canceller using adaptive IIR notch filter is presented. The method adjusts the notch parameter according to Sign-LMS standards. TMS320C50 digital signal processor is used to process in the fured-point number system. The experimental results show that the method can suppress acoustic feedback rapidly and effectively for different conditions.
