模态分析，获得采样数据的固有频率、各阶振型，阻尼比等，(Modal analysis, the natural frequency of the sampling data, each vibration mode damping ratio)

本程序的功能是：实现信号从时域到频域的快速傅里叶变换。(Realize the signal conversion from time domain to frequency domain.)

香农能量算法用于提取心音信号的包络。同时还有一个用来对信号进行训练用的程序，主要是提取信号的特征值，以实现信号的分类识别(Shannon energy algorithm is used to extract the heart sound signal envelope. As well as a training signal is used for the procedure used mainly to extract the value of the signal characteristics in order to achieve signal classification and recognition)
