I am currently trying to write some fourier transform algorithm. I started with a simple DFT algorithm as described in the mathematical definition:
I am trying to perform an inverse and a pseudo-inverse filtering in the frequency domain. However I am having trouble accessing DFT coefficients and multiplying DFT matrices afterwards, since I got c
I studied the Cooley Tukey algorithm and I understood it. I got everything in the CUDA convolutionFFT2D example till these kernels:
I\'m reading how the cooley tukey method works, but I have a few problems with the following python script:
I have been searching everywhere to find a reliable method to calculate the FFT of an audio byte stream received by a native function in android SDK (through eclips开发者_StackOverflow社区e IDE). I ha
Having problems compiling this class. I\'m working through a book on java and this is one of the exercises, and they provide most of the code. So this is basically a stock class provided by the book.
I\'ve got a FFT magnitude spectrum and I开发者_开发知识库 want to create a filter from it that selectively passes periodic noise sources (e.g. sinewave spurs) and zero\'s out the frequency bins associ
I\'ve been playing around a little with the Exocortex implementation of the FFT, but I\'m having some problems.
