Examples of low-pass filters Acoustic A stiff physical barrier tends to reflect higher sound frequencies, and so acts as a low-pass filter for transmitting sound. When music is playing in another room, the low notes are easily heard, while the high notes are attenuated.Electronic In an ...
一、高低通滤波器的作用原理 高低通滤波器的作用是在音频信号中过滤掉一定频率范围内的信号成分,只保留特定的频率范围内的信号。高通滤波器(High-pass Filter)是指只允许高于指定截止频率的信号通过,而低于该频率的信号被阻隔。低通滤波器(Low-pass Filter)则是只允许低于指定截止频率...

The beta parameter trades the rejection of the low pass filter against the transition width from passband to stop band. Larger Beta means a slower transition and greater stop band rejection. See Rabiner and Gold (Theory and Application of DSP) under Kaiser windows for more about Beta. The foll...
