dtmf
- 本程序用于检测音频文件中是否具有DTMF信号,若有则将其检出。 程序首先使用Goertzel算法求出以FRAMESIZE(默认200)为大小的一帧数据在8个DTMF频点上的能量。 对Goertzel算法的改进,对于系数的计算不是采用2*cos[2*pi*k/N],而是采用2*cos[2*pi*fn/fs],这样能够降低误差。 确定了8个频点的能量后运用一系列判决门限来确定有没有DTMF信号,以及信号是什么。 -This procedure used to detect wh

- DTMF(双音多频)是用两个特定的单音频组合信号来代表数字信号的一种编码技术。两个单音的频率不同,代表的数字或实现的功能也不同。可采用8种频率代表电话机上的16个按键,10个数字键0~9和6个功能键*、#、A、B、C、D。具体的频率组合见参考书。要求: (1) 根据键盘输入的符号,利用MATLAB产生对应的DTMF信号;(2) 分别利用FFT算法和Goertzel算法计算该DTMF信号的频谱并画出频谱图;(3) 根据频谱图确定DTMF信号所代表的符号是否和输入的符号一致。 -DTMF (

Goertzel
- Goertzel基本算法在每次采样后立即进行处理,在每个第N次采样进行一次音调检测。在采用FFT算法时,我们要对成块的采样进行处理,但这并不意味着必须按块来处理数据。数字处理的时间很短,因此如果每次采样都存在一次中断,那么这些数字处理完全可以在中断服务程序(ISR)内完成。或者,如果系统中存在采样缓存,那么可以持续采样,然后进行批处理。-Goertzel basic algorithms in each sample immediately after processing, in each o
