精确估计双音多频信号的频率
◆通过不同窗函数，画语图分析双音多频信号
◆估计各个时段的频率，频谱分辨率要求≤10Hz（含戈泽尔算法）
◆检测信号包含的电话号码信息
-Accurate estimation of the frequency of a dual tone multi frequency signal.
◆Through different window functions, the picture is drawn to analyze the dual tone multi frequency signal.
◆Each time the frequency estimation, spectrum resolution less than 10Hz (Goertzel algorithm).
◆The detection signal contains the phone number information.
