这是一个使用希尔伯特黄变化提取心音包络的程序(extract the envelope of the heart sound based on hilbert-hung transfrom)

本书基于MATLAB 5.2版，提供了使用MATLAB的实践性指导。(The book based on the MATLAB 5.2 version, the use of MATLAB to provide practical guidance.)

说明：  用双线性变换法设计一个Butterworth低通滤波器，要求其通带截止频率100Hz，阻带截止频率200Hz，通带衰减小于2dB，阻带衰减大于15 dB，采样频率为500 Hz。(Using bilinear transformation to design a Butterworth low-pass filter, requiring that their pass-band cutoff frequency 100Hz, stopband cutoff frequency 200Hz, pass-band attenuation is less than 2dB, stop-band attenuation greater than 15 dB, a sampling frequency of 500 Hz.)

方位估计是阵列信号处理的重要内容，使用单个矢量传感器估计信号方位近几年才发展起来(DOA estimation array signal processing is an important aspect of using a single vector-sensor estimate signal directions only in recent years developed)

说明：  说明： 该课题为基于bp神经网络的中文汉字识别系统，可以用手写板写，现场识别。有界面GUI操作。另外可识别汉字，字母，数字等均可。(Explain: This project is a Chinese character recognition system based on BP neural network, which can be written on handwritten board and recognized on the spot. There is interface GUI operation. In addition, it can recognize Chinese characters, letters, numbers, etc.)
