Simulink Simulation: AM, FM, and Other Modulation Techniques with Implementation Examples

Simulink simulation serves as a widely adopted tool for modeling and modulating various signals, including amplitude modulation (AM), frequency modulation (FM), and other modulation schemes. Through Simulink simulations, engineers can perform detailed signal analysis and research to optimize system performance while enhancing signal transmission quality and efficiency. The implementation typically involves using Simulink's Communication Blockset, where key components like the AM Modulator Passband block (for carrier frequency specification and modulation index control) and FM Modulator Passband block (for frequency deviation parameter configuration) are essential for accurate signal representation. The simulation environment allows for real-time parameter adjustment through MATLAB scripting integration, enabling systematic performance evaluation using spectrum analyzers and BER (Bit Error Rate) test instruments. Simulink's application scope extensively covers communication systems, electronics, control engineering, and multiple interdisciplinary fields. Both in academic research and engineering practice, Simulink simulation proves to be an invaluable tool that helps engineers and researchers better understand and implement various modulation techniques through visual block-diagram modeling and automatic code generation capabilities for hardware deployment.
