inverse fast fourier transformation (IFFT)

While a Fast Fourier Transform (FFT) transforms a time domain signal into a frequency domain signal, the Inverse Fast Fourier Transform (IFFT) reverses this process. An IFFT transformation is a reverse transformation in which a frequency-related signal from the frequency domain is transformed into a time-related signal in the time domain.
