WebThe radix-2 decimation-in-time and decimation-in-frequency fast Fourier transforms (FFTs) are the simplest FFT algorithms. Like all FFTs, they gain their speed by reusing the results of smaller, intermediate computations to compute multiple DFT frequency outputs.The radix-2 decimation-in-time algorithm rearranges the discrete Fourier transform ...
