simple programs for me to understand basic DSP algorithms
This is intended to be a collection of basic DSP algorithms Currently implemented are: -Convolution/Cross-correlation in quadratic (O(N^2)) time -FFT (non-recursive Cooley-Tuckey algorithm without extra storage) -some bit reversal routines for bytes and integers TODO: -FFT for real-only data -Convolution/Cross-correlation using fft in linearithmic (O(N*log(N)) time -some demodulation algorithm for sound frequency detection -demos: polynomial multiplication 2d convolution for images (blur, edge detection) audio effects (delay, shift etc) -documentation and comments
