本文主要阐述了DTMF的原理及如何在MATLAB上产生DTMF信号，主要涉及到电话拨号音合成的基本原理及识别的主要方法，利用 MATLAB 软件以及 FFT 算法实现对电话通信系统中拨号音的合成与识别。并进一步利用 MATLAB 中的图形用户界面 GUI 制作简单直观的模拟界面。 能够利用矩阵不同的基频合成 0 － 9 不同按键的拨号音，并能够对不同的拨号音加以正确的识别，实现由拨号音解析出电话号码的过程，完成对电话拨号音系统的简单的实验仿真。-This paper described the principle and how DTMF in MATLAB to generate DTMF signals, mainly related to the telephone dial tone of the basic principles of synthesis and identification of the main methods, the use of MATLAB software and the FFT algorithm on the telephone communication system dial tone Synthesis and Recognition . And further the use of MATLAB in the production of graphical user interface simple and intuitive GUI interface simulation. Able to take advantage of matrix synthesis of different fundamental frequency 0- 9 different keys of the dial tone and be able to different dial tone to be the correct identification, the dial tone from a telephone number to resolve the process of completion of the telephone dial tone system, a simple experiment simulation

BOrgTec GPSRS232 ActiveX Control提供如下特性：分析NMEA串，也就是说包含在NMEA序列里的数据将被提取出来。数据由ActiveX事件提供。NMEA序列从与PC串口连接的GPS接受器中获得。可以配置串口的参数，以与多种GPS接受器进行通讯。配置ActiveX Control显示数据的字体颜色和计量单位。这些特性使你在应用中加入GPS功能变得简单。适用语言：D5-BOrgTec GPSRS232 ActiveX Control provides the following features: Analysis of NMEA string, that is included in the sequence in the NMEA data will be extracted. Data provided by the ActiveX events. NMEA sequence from the PC serial port to connect with the GPS receiver gain. Serial port parameters can be configured to a variety of GPS receivers and communication. ActiveX Control to configure the font color display data and units of measurement. These features allow you to add in the application of GPS functionality simple. The application of the language: D5
