通过matlabGUI设计电话拨号界面，实现电话双音多频DTMF的仿真，根据所给数据制作拨号盘，并产生相应音调。-Design by matlabGUI dial interface to achieve multi-frequency DTMF tone telephone simulation, produced according to the data dial, and generates tones.

电话DTMF编码解码仿真。有线方式编解码：P2口为显示，P3口为编码的输出-Telephone DTMF codec simulation. Wire codec: P2 mouth for the show, P3 mouth for encoding output

用MATLAB仿真DTMF,分为生成和检测两个部分-use MATLAB to simulate the DTMF including generation and detection

DTMF报告和代码，基于simulink仿真，通过GUI调用m代码和simulink，可加噪音。-DTMF reports and code, based on simulink simulation, call m code and simulink through GUI, can add noise.
