Ipps fft
WebThe functions ippsFFTInit_R and ippsFFTInit_C are declared in the ipps.h file. These functions initialize the FFT specification structure ppFFTSpec with the following parameters: the transform order, the normalization flag , and the specific code hint. The order argument defines the transform length. WebTo use the FFT functions, initialize the specification structure which contains such data as tables of twiddle factors. The initialization functions create the specifications for both forward and inverse transforms. The amount of prior calculations is thus reduced and the overall performance increased.

Accordingly, the power in each bin depends on the width of the bin.
