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.)

说明： 水电站中长期优化调度主要是在满足电力系统出力要求以及下游综合用水要求等的前提下，合理地安排水库各个月份的发电流量，使得调度期内的总发电量最大。即在给定预报入库流量过程线、下游综合用水流量过程线、调度期起始水位和终止水位等条件下，通过总水量的合理运用使调度期内水电站的总发电量最大。(Long-term optimal operation of hydropower stations mainly in the power system to meet the output requirements, and integrated water requirements downstream of the premise, reasonable arrangements for generating reservoir flow each month, making the scheduling period, the largest amount of total power generation. That is forecast in a given inflow hydrograph, downstream water discharge hydrograph synthesis, scheduling and termination of the initial water level and water level conditions, the total amount of water through the rational use of the scheduling period, the total generating capacity of the largest hydropower station.)
