finite impulse response filter meaning in Chinese

有限冲激响应滤波器
有限脉冲反应滤波器
有限脉冲响应滤波器

The echo canceller includes an adaptive finite impulse response filter that generates an adaptive filter weight vector
此?音消除系统由一适应性有限脉冲响应滤波器所组成，它能产生一组适应性滤波器权值向量。
Because period narrow band signals are the main part of background noises , this thesis uses hardware description language to design a multi - band finite impulse response filter ( fir ) and downloads the program into filed programmable gate array to eliminate the period narrow - band interferences in the background noises
3 )在现场环境中，背景干扰主要是周期性的窄带，本文利用硬件描述语言( vhdl )设计了一个多带fir有限冲击响应滤波器。应用到可编程逻辑器件中，消除了背景噪声中的周期性干扰，为信号的进一步处理提供尽可能干净的信号。
