调频信号2FSK的实现

本课题主要研究数字调频信号2FSK的原理性质和实现方法。使用一种伪随机的数字信号发生电路充当发送数据。在PROTEUS仿真环境下搭建伪随机的数字信号发生电路和发送的调制电路（用乘法器实现）。所设计的接收电路能够对发送的信号解调，并能够比较发送和解调后的数据。

Realization of Frequency-Modulated Signal 2FSK

This topic main research numeral frequency-modulated signal 2FSK principle nature and realization method.Uses one kind of pseudo-random the digital signal to have the electric circuit to act as the transmission data.Builds the pseudo-random digital signal to have the electric circuit and the transmission tone circuit （realizes with muhiplier）.under the Proteus simulation environment Designs the accepting circuit can to the transmission signal demodulation, and can compare transmits and demodulates after the data.
