Inverse Fourier transform
Description
"Inverse Fourier transform" calculates the discrete inverse complex Fourier Transform according to
out of the given signal X (supposed to be the Fourier transform of y) of length N (in samples) using a Fast Fourier Transform (FFT) algorithm.
Tips
The type of FFT algorithm used can be set in the Basic Options menu.
Macro Synopsis
y = InvFFT(x);
signal x,y;
Note that x is always a complex signal, while y can be a complex signal or a standard single-channel signal.
