DFT-IDFT module in MATLAB

By Preet Rajpara

Module to find the DFT and IDFT of sequences x(n) in MATLAB language without using Inbuilt functions.

This module helps in finding the DFT (Discrete Fourier Transform) and IDFT (Inverse Discrete Fourier Transform) of sequences x(n).

The module is written in MATLAB language. And inbuilt functions to find DFT and IDFT are only used to verify answers from my function.

The module can be used in different signal processing projects in order to do DFT in of signals and then using IDFT it can be Inversed.

Moreover, DFT is the most powerful tool while processing digital signals and allows us to find the spectrums of finite-duration signals.
