基于DSP的DTMF的信号检测与识别

基于DSP的DTMF的信号检测与识别

基于DSP的DTMF的信号检测与识别摘要双音多频DTMF(Dual Tone Multi-Frequency)信令在全世界范围内得到广泛应用,将DTMF信令的产生与检测集成到含有数字信号处理器(DSP)的系统中,是一项较有价值的工程应用。

本文给出一种实现方案,阐述DTMF信令的产生与检测的基本原理:用两个二阶数字正弦振荡器产生DTMF信号,并通过Goertzel算法实现DTMF信号检测。

本论文是在TI公司定点DSP芯片TMS320C54x系列中的实现DTMF信号的检测,采用DSP技术既增加了系统的功能、灵活性,又降低费用,克服了硬件电路实现检测的缺点。

因为本课题着重于DTMF信号的检测,所以DTMF信号的产生是通过音频处理软件Cool Edit Pro产生,然后将DTMF信号通过PC音频接口传输到AIC23B的接口,经过A/D采样编码后送到DSP进行信号检测,最后单片机将结果通过DSP 的HPI接口读取再通过单片机的串口传输到PC的串口调试助手上显示出来。

最后结果,结合Goertzel算法,DSK5402板能够实现对DTMF信号的解码,通过串口显示到串口调试助手上,达到了本论文的研究目的。

用单片机实现DTMF信号译码

用单片机实现DTMF信号译码

用单片机实现DTMF信号译码DTMF信号首先用于电话的拨号系统,在频率编码遥控系统及数据编码传输中的应用也很普遍。

目前的DTMF译码器中,大多采纳通用集成器件(单音译码和组合门电路)或专用DTMF信号译码(如MC145436等)组成译码电路。

在无数状况下,DTMF译码器输出的数据仍需送入举行相应的运算及处理,进而控制其它各种设备的动作。

因此,假如能找到一种基于单片机的DTMF信号的译码算法,再辅之以容易的整形电路就可以,既可省去成套译码电路,又能达到简化电路降低成本的目的。

本文所要介绍的,就是这种构想的初衷,结果通过计算机计算数据论证认为彻低能够达到设计要求。

2、DTMF信号频率组成及整形前DTMF信号的幅值密度在DTMF信号中,16个命令键均由两个单音频率信号组合(见表1)。

单音频率有两组,高频组为(1209Hz、1336Hz、1447Hz、1633Hz),低频组为(697Hz、770Hz、852Hz、941Hz),每个命令键,对应的都是一个高频组的频率和一个低频组的频率的组合。

以“*”号命令键为例:其DTMF信号是由941Hz的低频组信号和1209Hz的高频组信号组成。

图1为其频谱图。

表1 DTMF信号频率组成表从图1中可以看出,“*”号命令键的DTMF信号在941Hz和1209Hz处有谱线。

在抱负条件下,可计算出频谱密度函数X(f)在f=941Hz和1209Hz时的模值为|X(941)|,|X(1209)|,即它们模值均不为零。

也就是说,要是同时存在频谱密度函数模值为|X(941)|,|X(1209)|,并且它们模值均不为零时,其表征的键号为“*”。

以此类推(见表1),可分离计算出低频组信号|X(697)|、|X(770)|、|X(852)|、|X(941)|和高频组信号|X(1209)|、|X(1336)|、|X(1447)|、|X(1633)|的模值。

假如高、低频组中均各自有一个X(f)的模值不为零,则再通过f在表1查找出其表征的命令键。
