双音多频，由高频群和低频群组成，高低频群各包含4个频率。一个高频信号和一个低频信号叠加组成一个组合信号，代表一个数字。DTMF信号有16个编码。利用DTMF信令可选择呼叫相应的对讲机。(Dual tone multi-frequency, high-frequency and low-frequency group composed of groups, high-frequency group contains four frequencies each. A high-frequency signal and a low frequency signal is superimposed to form a combined signal representative of a number. DTMF signal has a 16 code. DTMF signaling to the appropriate use of the intercom call.)

介绍了常见的时频分析方法，包括短时傅里叶变换，Wigner-Ville分布以及小波变换等，结合MATLAB，引导读者如何运用其来进行时频分析(Describes the common time-frequency analysis methods, including short time Fourier transform, Wigner-Ville distribution and wavelet transform, combined with MATLAB, to guide the reader how to use it to carry out time-frequency analysis)

说明：  信号的时间宽度和频率带宽反映的是 、 围绕 和 的扩展程度，信号的带宽（ ）完全由幅度、幅度的导数及相位的导数所决定。称T和B分别为信号 的时宽和带宽，TB称为时宽－带宽积,。此程序用于计算信号的时间宽度和频率带宽。(Signal time width and frequency bandwidth of reflected that and it spreads around the signal bandwidth () completely by the magnitude, amplitude and phase derivative of the derivative of the decision. Called T and B respectively when the signal width and bandwidth, TB is called when the wide- bandwidth product. This program is used to calculate the width of the signal time and frequency bandwidth.)
