I'm still a little confused with your statement: In "natural" non-bit reversed order, the 1st positive frequency should be in bin 1.  The "1st" negative frequency...

CMSIS DSP ARM Complex FFT output arrangement

New thread started 5 years ago
I'm trying a snippet of code, based on CMSIS DSP Library, that take 2 quadrature (I & Q) signals and do complex fft. (pseudo code)FFT_SIZE = 128I signal [128]Q...
