fft

Description:

public void fft (int16 timedata, S16Complex freqdata)

This performs the FFT on timedata and puts the result in freqdata.

timedata must have as many samples as specified with the len parameter while allocating the S16 instance with S16.

freqdata must be large enough to hold len/2 + 1 S16Complex frequency domain samples.

Parameters:

this

S16 instance for this call
timedata

Buffer of the samples in the time domain
freqdata

Target buffer for the samples in the frequency domain
