stfft online with Winfy

We have hosted the application stfft in order to run this application in our online workstations with Wine or directly.

Quick description about stfft:

Fast fourier transform algorithm written on IEC-61131-3 Structured text programming language for programmable logic controllers.

Algorithm is split-radix FFT. StFFT is iterative contrary to more common recursive approach. Iterative solution was chosen because PLCs don't have support for recursion. For compatibility with as many as possible PLC models, algorithm have dependency only on sine and cosine functions.
