omprehensive collection of MATLAB experiments for Analog & Digital Communication (ADC) and Digital Signal Processing (DSP), including modulation techniques, signal convolution, and filter designs with visualized outputs.
MATLAB Communication and Signal Processing Experiments
This repository contains a comprehensive collection of MATLAB experiments for Analog & Digital Communication (ADC) and Digital Signal Processing (DSP). Each experiment includes the source code and its corresponding output waveform.
📂 Repository Structure
The project is organized into two main sections:
- Analog_and_Digital_Communication: Covers modulation, demodulation, and pulse techniques.
- Digital_and_Signal_Processing: Covers signal operations, convolution, correlation, and filter design.

🚀 How to Run
- Open MATLAB.
- Navigate to the desired folder (
Analog_and_Digital_CommunicationorDigital_and_Signal_Processing). - Open the
.mfile you wish to run. - Click the Run button or press F5.
📝 Note for VS Code Users
If you prefer to run these files within VS Code, ensure you have:
- A Licensed MATLAB installed on your system.
- The MATLAB Extension for Visual Studio Code installed.
Recommendation: While VS Code is excellent for editing, it is highly recommended to run these experiments directly in the MATLAB IDE for the best experience with figure plotting and debugging.
