MATLAB Implementation of FM Modulation Model using Simulink

I conducted experiments using the FM modulation model in Simulink. This model demonstrates fascinating modulation techniques where I implemented key components including frequency deviation modulation and phase modulation. The implementation involves configuring the Frequency Modulator Passband block with specific carrier frequency and frequency deviation parameters, while using a Message Signal source (typically a sine wave or audio signal) to drive the modulation process. Through systematic parameter adjustments, I explored the model's performance characteristics by varying modulation indices and observing the resulting spectrum using Spectrum Analyzer blocks. The experiment provided deep insights into FM modulation principles, including Carson's rule for bandwidth calculation and the signal-to-noise ratio improvements inherent in frequency modulation. I gained substantial knowledge about Simulink's RF modulation capabilities, particularly in configuring solver settings for RF simulations and using visualization tools like the Time Scope and Spectrum Analyzer for waveform analysis. I welcome technical discussions on optimization approaches, including potential enhancements using MATLAB scripting for automated parameter sweeping or implementing advanced modulation schemes like pre-emphasis/de-emphasis filters to improve signal quality.
