Hi all, My waveform (1024 current reading in [A], @1s) needs to be processed for frequencies using FFT method. The current values are in range between pA and mA ranges. There is an existing tech-talk exchange on FFT from about 5 years ago that discuss FFT3, fftw, and waveProc. FFT3 based: http://www.aps.anl.gov/epics/tech-talk/2011/msg01143.php http://www.fftw.org/fftw3_doc/Complex-DFTs.html#Complex-DFTs
The github fftw development:

The waveProc is bit dated (2004?) http://www.aps.anl.gov/epics/download/modules/index.php Any newer solutions and suggestions? Kazimierz Gofron NSLS-II Controls Group Brookhaven National Laboratory (p) +1 (631) 344 5283 (f) +1 (631) 344 8085 |
