2psk信号的产生和其瞬时幅度，瞬时相位，瞬时频率的提取-2psk signal generation and its instantaneous amplitude, instantaneous phase, instantaneous frequency extraction

用VC++MFC编写的上位机软件，它可以通过rs232串口接收下位机发送来的数据并实时显示，还可以对波形作频率幅度检测，还可以做更多普通示波器做的事情。-Prepared using VC++MFC software, it can be through the RS232serial port to receive the client to send data and display in real time, but also on the wave frequency amplitude

输入信号通过线性时不变系统，幅度响应和频率响应失真分析MATLAB仿真。-the input signal pass the LTI system,simulate the distortion of amplitude response and phase response.
