feedback suppressor meaning in English
反馈抑制器
Examples
- However , most of automatic feedback suppressors in domestic market are imported from oversea and expensive
但是,目前市面上的自动声反馈抑制产品,大多是国外品牌,价格不菲。 - We must develop automatic feedback suppressor with own intellectual property to possess enormous competitive strength of marketing
因此,如果研制出具有自主知识产权的自动声反馈抑制器,将具有强大的市场竞争力。 - 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
与传统的自适应的方法比较,增加了系统识别和驻波抑制的相关模块,一定程度的提高了传声增益。 - 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
本方案具有如下技术特点:第一,采用chirp - z变换( czt )算法与fft算法相结合对声反馈进行检测,并利用声反馈信号建立前期的时频特征,设立判定条件。 - 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
分别是:第一,基于滤波器组和频域采样法设计滤波器的方案。利用小波分析和重构算法对信号进行分解并最后重构,同时在频域直接采用频域采样法设计滤波器对啸叫的频点进行陷波处理。
