How to use the IFFT function in Matlab?

X = ifft( Y ) computes the inverse discrete Fourier transform of Y using a fast Fourier transform algorithm. X is the same size as Y . If Y is a vector, then ifft(Y) returns the inverse transform of the vector. If Y is a matrix, then ifft(Y) returns the inverse transform of each column of the matrix.

Is FFT the same as IFFT?

FFT (Fast Fourier Transform) is able to convert a signal from the time domain to the frequency domain. IFFT (Inverse FFT) converts a signal from the frequency domain to the time domain.

What is meant by IFFT?

2 Inverse Fast Fourier Transform (IFFT) IFFT. IFFT is a fast algorithm to perform inverse (or backward) Fourier transform (IDFT), which undoes the process of DFT.

What is DSP IFFT?

Description. The dsp. IFFT System object™ computes the inverse discrete Fourier transform (IDFT) of the input. The object uses one or more of the following fast Fourier transform (FFT) algorithms depending on the complexity of the input and whether the output is in linear or bit-reversed order: Double-signal algorithm.
