摘　　要：根据遥测中频PCM/FM信号的解调原理,介绍了FM解调及自动频率控制(AFC)设计的理论架构和实现方法,通过理论分析、公式推导和Matlab仿真等手段证明了方法的正确性,在此基础上完成VHDL程序设计,最后进行了仿真测试和实验验证。仿真结果和实验结果证明了该实现方法的可行性。The method of FM demodulation of telemetry PCM/FM signal is given. By theoretical analysis, formula deduction and Matlab simulation, the correctness of this FM demodulation and AFC method is confirmed. The VHDL code is designed according to the mathematical model. Finally, computer simulation and experimentation are provided and the result proves the feasibility of this implementation approach.
