变采样和多相滤波器的实现。本程序实现了一个变采样程序,中间设计滤波器设计和插值抽取。其中滤波器设计用的是窗函数法,根据要求设计窗函数,得到窗函数的长度。接着是插值,滤波,抽取,得到最后变采样之后的波形文件、另外对比了用直接卷积和多相分解卷积两种方法最后的结果。

零延时卷积算法实现,基于fft变换。Efficient Convolution Without Latency by
William G. Gardner-It is well known that a block FFT implementation of convolution is vastly more efficient than the direct
form FIR filter. Unfortunately, block processing incurs signifi
