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:

The github fftw development:

The waveProc is bit dated (2004?)

Any newer solutions and suggestions?
