用matlab实现低通滤波器。采用的是FIR低通滤波器实现。(Low pass filter with matlab. Using the FIR low-pass filter.)

本毕业设计用Matlab中的建模仿真工具Simulink对通信原理实验进行仿真。作为系列实验的第一部分，包括模拟信号的线性调制解调(AM、DSB、SSB)过程、扰码与解扰实验和低通信号的抽样定理实验。论文中讲述了Matlab的基础知识、Simulink仿真操作方法以及在通信系统中的应用，对被仿真实验的基本原理也进行了简要介绍。 通过本设计对构造通信原理虚拟实验室这一课题进行了初步的探索。(design with the graduation of Matlab Simulink modeling and simulation tools for Progressive Communications principle experiment OK simulation. As the first series of experiments, including a linear analog signal modulation and demodulation (AM, DSB, SSB) process. encryption code and experimental communications, and low sampling theorem experiment. Papers on the basis of Matlab knowledge, Simulink operation and the communication system, the application Simulation experiments on the basic principle was also briefly introduced. Through the design of communication principle structure of the virtual laboratory conducted a preliminary exploration.)
