- 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
