说明：  DTMF的PDF说明文件，从原理到应用方法进行了详尽的叙述，使人理解双音多频的概念和使用方法(DTMF PDF Document from the application of the principle carried out a detailed narrative that people understand DTMF the concept and use)

设计一个切比雪夫滤波器，要求通带截止频率 ，通带最大衰减 ，阻带截止频率 ，阻带最小衰减 。要求绘出滤波器的幅频特性曲线。(Design a Chebyshev filter, the passband cutoff frequency required, the maximum passband attenuation, stopband cutoff frequency, stopband minimum attenuation. Requirements of the filter amplitude-frequency characteristic plotted curve.)

选择五个不同频段的信号对其进行频谱分析，根据信号的频谱特征设计五个不同的数字滤波器，将五路信号合成一路信号，分析合成信号的时域和频域特点，然后将合成信号分别通过设计好的五个数字滤波器，分离出原来的五路信号，分析得到的五路信号的时域波形和频谱，与原始信号进行比较，说明频分复用的特点。(To select one of five different band signal spectrum analysis and design of five different digital filter based on the spectral characteristics of the signal, the the Rd signal synthesizing all the way to the signal analysis in time domain and frequency domain characteristics of the synthesized signal, and then the synthesis signal by five digital filter designed, separated original signal Rd, the time-domain waveform and spectrum analysis the Rd signal is obtained, to be compared with the original signal, the frequency division multiplexed with the characteristics.)
