一种2FSK解调器的VHDL实现

A VHDL Implementation of 2FSK

文中首先介绍调制、解调的原理,以及FSK信号的过零检测法,并对MAXPLUS2软件进行简单介绍,然后重点介绍FSK解调器的实现方法,最后通过MAXPLUS2对代码进行仿真,并实现对FSK信号的解调。

This paper first describes the principles of modulation and demodulation, including zero-crossing detection of FSK signal, and then gives a brief introduction of MAXPLUS2 software. It focuses on implementation of FSK demodulator. Finally simulation on the code realizes the demodulation of FSK signal through MAX PLUS2.
