This project implements audio signal processing using Discrete Fourier Transform (DFT) in MATLAB. The script processes an audio signal, adds noise, and applies low-pass, high-pass, and band-pass ...

Operations-on-audio-signal Spectrum Internship/ Task-2 of MATLAB Write a program in MATLAB that will modulate and de-modulate a signal and plot it accordingly. Follow the steps First ask the user to ...

While there are many examples on the Web of using DFT functions that show how to make a spectrum for signal analysis or power spectral density for noise analysis, many are not fully accurate, hard to ...
