This is a repository where I added my DSP codes that have written in Matlab (without built-in function). I have also commented inside every code so that it will become helpful for newbies. Also added cross-check using Library Function.

Digital-Signal-Processing-Codes

This is a repository where I added my DSP codes that have written in Matlab (without built-in function). I have also commented inside every code so that it will become helpful for newbies. Also added cross-check using Library Function. Codes included: Basic signals, Convolution, Correlation(Cross & Auto), DFT, IDFT, FIR Filter Response, Divide & Conquer FFT, Radix-2 FFT
