DTMF
- DTMF(双音多频)信号的产生和检测 1、程序分两部分,前半部分为DTMF 产生,后半部分为DTMF 检测。 2、DTMF 产生中用数组in设定键值,数组长度为16,范围0~15,可人工改写; 3、数组xr为产生的行频信号,长度为102,32位浮点型; 数组xc为产生的列频信号,长度为102,32位浮点型; 数组x为产生的双音频信号,长度102点,32位浮点型; 4、数组z为DTMF检测中能量模板 ,以完成按键的行位置及列位置检测; 6、变量outkeycol

DTMF
- DTMF(Dual Tone Multi Frequency)信号是音频电话的拨号信号。由美国AT&T贝尔实验室研制, 双音多频信号编码技术易于识别,抗干扰能力强,发号速度快,且比用modem进行远程传输的方法更为经济实用,因此这种拨号方法取代了传统的脉冲拨号。 电话中的双音多频信号有两种用途:一是用于双音多频信号的拨号,去控制交换机接通被叫的用户电话机;二是利用双音多频信号遥控电话机各种动作,如播放留言,语音信箱。这些都离不开DTMF信号的产生。 有详细的需求分析 功能说明 流程图及代
