"MATLAB SIMULINK下的FM调制解调原理与仿真"

In the "FM Modulation and Demodulation Explanation Based on MATLAB SIMULINK" PDF, the author provides a comprehensive overview of frequency modulation (FM) and its application in communication systems. The document discusses the process of generating modulated signals using MATLAB SIMULINK, and the principles of FM modulation and demodulation. The PDF emphasizes the importance of understanding analog baseband signals and their modulation to adapt the low-pass spectrum to the carrier frequency for transmission through the channel, and the subsequent demodulation to recover the original electrical signals. The author showcases the use of frequency modulation to achieve this objective, and provides a detailed explanation of the modulation and demodulation process. The document also highlights the application of SIMULINK toolbox for the design and simulation of FM signals. It discusses the utilization of SIMULINK's rich templates and the author's grasp of communication principles to complete the modulation and demodulation of FM signals. The use of a simple sine wave signal generator as the source and the simulation of FM modulation and demodulation principles is illustrated in detail. In summary, the PDF provides an in-depth exploration of FM modulation and demodulation, and demonstrates the application of MATLAB SIMULINK in designing and simulating communication systems. The knowledge of communication principles and the use of SIMULINK toolbox are highlighted as key components in achieving the modulation and demodulation of FM signals. Overall, the document serves as a valuable resource for individuals seeking to understand and apply FM modulation and demodulation in communication systems.
