Basically I want a filter that, for example, can attenuate 160Hz more so than 80Hz (second and first harmonics of E string respectively). I was planning on expanding on the IIR code above to get an appropriate filter response to acheive this (so those values of "a" are just values ...
Using fdatool, I have generated a lowpass filter with cutoff frequency of 200Hz and sampling frequency 48kHz. The order of the filter is specified and it is 10. The filter arithmetic is 16-bits fixed point. The filter is supposed to be used as a part of an equalizer. The...

可以。 对于N抽头的FIR,可以得到N evenly-spaced points of the frequency response by doing a DFT on the filter coefficients.但是,为了得到任意频率的频率响应,需要使用上边的公式。 2.2.4 FIR滤波器的DC增益指的是什么? DC(0 Hz)输入信号包含每个采样都为1.0。通过延时线后,输出是所有系数的和。因而,在DC...
