| 摘 要： | DTMF信号被广泛的应用在交互式控制中,如语言菜单、语言邮件、电话银行和ATM终端等。对于DTMF信号的产生、识别,普通的设计方案一般都采用专用的数字编解码芯片,成本高,体积大。本文论述在FLASH型超低功耗16位单片机MSP430中实现一类FIR滤波器WDF(wave digital filters),借助WDF滤波器良好的动态特性,使得MSP430的用户可以良好的解决DTMF编解码一类的应用问题。

| Abstract: | The MSP430 is an ultra-low-power 16-bit RISC mixed-signal processor from TI.it can provide the ultimate solution for battery-powered measurement applications.DTMF is widely used in communication,remote-control for its well-done properties,and it is also been used in mutual-control such as tele-bank and ATM terminals these years.In this paper,a FIR filter-WDF(wave digital filters)is implemented,which enable MSP430 users to solve special measurement problems like DTMF problems by means of robust digital filter algorithms. |
