Implementation of AM modulation and demodulation simulation through MATLAB M-file programming with code-level explanations of signal processing techniques
Detailed Documentation
This experiment utilizes MATLAB M-files to simulate AM modulation and demodulation processes. The implementation involves writing MATLAB code to generate AM modulated signals and demodulate them to recover the original signals. Key programming components include defining carrier wave parameters, implementing modulation algorithms using multiplication operations, and designing envelope detection or coherent demodulation methods. Through simulation, we can analyze how different parameters such as modulation index and carrier frequency affect signal characteristics. The MATLAB code typically involves signal generation functions, time-domain analysis, and visualization commands to observe waveform transformations during modulation and demodulation stages. This practical approach enhances understanding of AM communication principles while developing proficiency in MATLAB programming for signal processing applications.
