The implemented template class recursion has P levels. Every FFT calculation process runs from level P to level 1, while the level 1 is empty (Listing Three, in part one of this article). Some ...
A group of MIT researchers believe they’ve found a way to speed up audio, video, and image compression by improving on the Fourier Transform. They say the new algorithm is up to ten times faster than ...
This article presents two important DSP techniques, the overlap-add method, and FFT convolution. The overlap-add method is used to break long signals into smaller segments for easier processing. FFT ...
