在C#中为FFT，IFT，杉木设计提供帮助 [英] help for fft,ifft,fir design in c#

问题描述

我最近在一个数字信号处理项目(C#)中，需要使用FFT，IFFT，FIR滤波器设计，所有专家都可以给我相关链接的类库，非常感谢

How to implement the FFT algorithm[^]

有几种设计FIR滤波器的方法.看看:

There are several ways to design FIR filter. Take a look:
"Sinc FIR filter design".
The main idea is to find the set of numbers which have a "filtering properties". All you need to do is to convolve the initial signal with the gotten "set of numbers". So, the job you need to do can be made in the time domain (without FFT and IFFT).

我见过的最有用，最方便的FIR滤波器设计教程是此处.

The most useful and handy tutorial for FIR filter design I have ever seen is here.
