基于matlab的巴特沃斯低通滤波器设计程序(Matlab based on the Butterworth low-pass filter design program)

按键式电话如下图所示，当按下某一个键时会产生如图所示的相应的频率模拟信号，并通过对该信号频率的检测，识别出对应的按键。试通过编写一个数字信号分析程序，模拟完成上面的功能。(Touch-tone phone as shown below, when pressing a key will be generated as shown in the corresponding frequency analog signals and, through detection of the signal frequency to identify the corresponding button. Test through the preparation of a digital signal analysis program to simulate the function of the completion of the above.)

说明：  此程序给出信号的多分辨率分析（Multiresolution Analysis），即信号的多分辨率分解（Multiresolution Decomposition）方法及应用。该程序是一个多抽样率系统（Multirate System）举例，用M个的滤波器，将信号的频谱等分成M部分，使所得抽样频率降为1/M，然后再依据它们的“重要性”给一不同的bit数，那么所传输的bit流必然会进一步下降，起到压缩带宽的作用。(This program gives the signal of the multi-resolution analysis (Multiresolution Analysis), the multi-resolution signal decomposition (Multiresolution Decomposition) method and its application. The program is a multirate rate system (Multirate System) example, with M a filter, the signal' s frequency spectrum is divided into M parts, the proceeds of sampling frequency reduced to 1/M, then according to their &quot importance&quot to the bit of a different number, then the transmitted bit stream is bound to decline further, to play the role of bandwidth compression.)
