Description: 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 (Dual Tone Multi-Frequency) is a single with two specific combination of audio signals to represent a kind of digital signal coding techniques. Two monosyllabic different frequency, on behalf of the numbers, or the realization of the functions are also different. Eight kinds of frequency of use on behalf of telephone on the 16 keys, 10 numeric keys 0 ~ 9 and 6 function keys*,#, A, B, C, D. The frequency of specific composition of reference books. Requirements: (1) According to the keyboard input of symbols, the use of MATLAB have a corresponding DTMF signal (2), respectively, using FFT algorithm and the Goertzel algorithm DTMF signal spectrum and frequency spectrum draw (3) According to DTMF signal frequency spectrum to determine represented by symbols and input symbols unanimously.

Description: 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 whether an audio file with a DTMF signal, if so, what will be its detection. Procedures to derive the first use of Goertzel algorithm to FRAMESIZE [default 200] for the size of data in an eight point DTMF frequency energy. Of the Goertzel algorithm for the calculation of coefficients instead of 2* cos [2* pi* k/N], instead of using the 2* cos [2* pi* fn/fs], this can reduce the error. Identified eight frequency energy use after a series of sentences to determine the threshold has no DTMF signal, as well as the signal is.
