According to these background, we have proposed 3 auto acoustic feedback suppressor schems : scheme i. two major algorithms - the wavelets or filter banks theories and the frequency sample filter theory have been implemented to make up the scheme a adaptive acoustic feedback suppressor
分別是:第一，基於濾波器組和頻域采樣法設計濾波器的方案。利用小波分析和重構演算法對信號進行分解並最後重構，同時在頻域直接採用頻域采樣法設計濾波器對嘯叫的頻點進行陷波處理。 -
Scheme ii. a scheme based on acoustic system recongniton and adaptive filter. compared with the traditional adaptive feedback suppressor, this system has been added a new component, the residual echo suppressor component
與傳統的自適應的方法比較，增加了系統識別和駐波抑制的相關模塊，一定程度的提高了傳聲增益。 -
This paper proposes a design of automatic feedback suppressor based on dsp : firstly, combining fft algorithm with chirp - z transform to detect feedback rapidly and set up the judging conditions based on the feedback characteristics to locate feedback accurately
本方案具有如下技術特點:第一，採用chirp - z變換（ czt ）演算法與fft演算法相結合對聲反饋進行檢測，並利用聲反饋信號建立前期的時頻特徵，設立判定條件。
