Filtering Real Time Signals

Filtering Real Time Signals

Everybody tells you, that filtering signals (Real or Complex) is simple. In Fact they are right, the only problem usually comes to designing a good filter, choosing its architecture (FIR / IIR) and also the best implementation for filtration in the application....
Templated Kiss FFT for C++

Templated Kiss FFT for C++

I have been recently searching for a viable FFT library for my own development. There are libraries such as the FFTW, but they have their limitations – the GPL licence (General Public). This means, you are unable to use it in your own application...

FFT Implementation R2 DIT| R4 DIF | R8 DIF

First of all, I would like to point out,that I will not cover the mathematical background beyond the FFT (Fast Fourier Transform), which is in fact just an algorithm of fast calculation of the Discrete Fourier Transform (DFT). I will just concentrate on how the Radix...
Ocean FFT in Matlab

Ocean FFT in Matlab

I was always amazed how fantastic was the Ocean simulation from nVidia (Its a part of the CUDA toolkit). I did not understand how was it working, so I searched and in fact found many examples on the internet. All of the ocean wave animations use the statistics model...
