调制与解调是信号处理应用的重要内容,该文利用Matlab/Simulink对幅度调制与解调进行仿真和分析。首先采用MATLAB7.0语言编制脚本文件,对信号进行幅度调制和解调仿真,并且对调制前后和解调前后的信号波形和频谱分析,然后利用Simulink工具箱对其进行系统建模。通过运用Matlab/Simulink具体仿真实例,实现Matlab/Simulink同信号处理的有机结合,不仅是系统设计分析的有利工具,而且提高了课堂教学和实验效果。
Modulation and demodulation signal processing applications is an important part of the paper using Matlab / Simulink amplitude modulation and demodulation for simulation and analysis. Firstly, the script file was compiled by using MATLAB7.0 language, the signal was amplitude modulated and demodulated, and the signal waveform and spectrum before and after modulation and before and after demodulation were analyzed. Then the system was modeled by Simulink toolbox. Through the use of Matlab / Simulink simulation examples to achieve the combination of Matlab / Simulink and signal processing, not only is an advantageous tool for system design and analysis, but also improve the classroom teaching and experimental results.
