FM Signal Modulation and Demodulation using Simulink

When conducting simulations using Simulink in MATLAB, FM signal modulation and demodulation can be effectively performed. Simulink's built-in functionality enables modeling of FM signal generation and transmission processes, providing deeper insights into modulation and demodulation principles and methodologies. Key Simulink blocks for FM implementation include the Frequency Modulator Passband block for modulation and Frequency Demodulator Passband block for demodulation, which can be configured with parameters like carrier frequency and frequency deviation. The platform offers comprehensive tools and modules for analyzing and optimizing modulation/demodulation performance, allowing engineers to evaluate system characteristics through spectrum analyzers and BER (Bit Error Rate) calculators. By utilizing Simulink's graphical programming interface, users can quickly assemble communication systems using drag-and-drop components and simulate complex FM signal processing chains. This approach enables performance analysis through scope visualization and signal measurements, making Simulink an efficient, accurate, and reliable method for FM signal modulation and demodulation simulations.
