MATLAB Code Implementation for Analog Modulation and Demodulation

This repository contains comprehensive source code implementations for analog modulation and demodulation techniques. The code covers fundamental modulation schemes such as AM (Amplitude Modulation), SSB (Single Sideband), DSB (Double Sideband), PM (Phase Modulation), and FM (Frequency Modulation), along with their underlying principles and practical applications. Each modulation technique is accompanied by detailed algorithms and implementation specifics. The codebase includes multiple examples and practical demonstrations for each modulation type, featuring key MATLAB functions like ammod() and amdemod() for amplitude modulation, ssbmod() for single sideband implementation, and fmmod()/pmmod() for frequency and phase modulation respectively. These implementations showcase carrier signal generation, modulation index calculations, sideband filtering techniques, and demodulation recovery processes. The examples are designed to facilitate understanding of analog modulation/demodulation processes and methodologies through hands-on coding experience, making them suitable for both educational and research purposes in communication systems.
