The signal processing block
FFT calculates the Fast Fourier Transform of an input.
The input is
The output is
KxN which is the FFT of the input signal
MxN. The size
K is dependent on the mode and number
of points of the FFT.
Values with ☐ can receive external input.
Name specifies the name of the block.
Mode specifies the output of the FFT. The mode can either be
Full which produces the full point FFT, or
which produces a N/2-1 point FFT multiplied by two to give the correct level.
Points is the number of points in the FFT.
If the number of points is larger than the inputs
M, the input
M is zeropadded. If the number of points is lower
than the inputs
M then an average of multiple FFT's is calculated.
Window species the windowing used in the FFT. This can be chosen to one of the following:
Overlap specifies the overlap in points if multiple FFT are calculated.
Channels specifies the number of input(s)/output(s) the block will have.
