A Simple and Efficient FFT Implementation in C++: Part II

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 ...

Algorithm of the Cavity Length Demodulation for Optical Fiber F-P Sensors Based on Nuttall Window Four-spectrum-line Interpolation FFT

Abstract: When the fast Fourier transform (FFT) algorithm is used to analyze demodulate interference signal, nonsynchronous sampling of the interference optical spectrum would cause spectral leakage ...
