Description: This project allows you to learn communication systems in greater depth. It contains the Simulink files (*.mdl) which are block design files of various communication systems such as AM, DSB-SC, FM, PLL, Data Acquisition, Digital Data Transmission, PCM and Delta Modulation.
The idea here is to implement experiments of a traditional communication lab using Simulink.
Most of the block diagrams are self explanatory. More information on the systems and their implementation can be found in the word documents included in the lab directories-This project allows you to learn communication systems in greater depth.

Description: 本系统以51单片机为控制核心，由正弦信号发生模块、功率放大模块、调幅（AM）、调频（FM）模块、数字键控（ASK，PSK）模块以及测试信号发生模块组成。采用数控的方法控制DDS芯片AD9850产生0Hz－30MHz正弦信号，经滤波、放大和功放模块放大至6v并具有一定的驱动能力。测试信号发生模块产生的1kHz正弦信号经过调幅（AM）模块、调频（FM）模块，对高频载波进行调幅或调频。二进制基带序列信号送入数字键控模块，产生二进制PSK或ASK信号，同时对ASK信号进行解调，恢复出原始数字序列。
另外，本系统从简单、调整方便、功能完备为出发点，基本实现了设计中的要求，波形输出较稳定，且精度较高。本设计还配备有LED显示屏、键盘，提供了友好的人机交互界面。
