| Abstract: | 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. |
