轴承信号小波变换，四层小波包分解，提起频带能量(Bearing wavelet transform)

Matlab实现绘制任意自由曲线，实现Photoshop中的钢笔路径功能，用光顺连接的B样条/贝塞尔曲线实现，鼠标点击生成控制点，拖动形成任意曲线。可描绘多路径，也可旋转、平移、缩放。经调试可用。(Matlab achieve rendering arbitrary free curve, realize the pen path function in Photoshop, with the light of the B spline/Bessel curve, the mouse click to generate control points, drag to form any curve. Can depict many paths, but also can rotate, translation, scaling. Debug available.)

说明：   1.录制一段自己的语音信号，并对录制的信号进行采样； 2.画出采样后的语音信号的时域波形和频谱图； 3.给定滤波器的性能指标，采用窗函数法和双线性变换法设计滤波器， 并划出滤波器的频域响应； 4.用该滤波器对采集的信号进行滤波，画出滤波后信号的时域波形和频谱， 并对滤波前后的信号进行对比，分析信号的变化； 5.回放语音信号； 6.设计一个信号处理系统界面(1. Recorded their own voice for some signal, and recording the signal sampling 2. Draw samples of the voice signal after the time-domain waveform and frequency spectrum 3. Given filter performance indicators, using a window function method and dual- Design of linear transformation filters, and draw the filter frequency response 4. to use the filters on the collected signal filtering, after filtering the signal to draw the time-domain waveform and spectrum, and filtering of signals before and after contrast, analysis of signal changes 5. playback voice signal 6. to design a signal processing system interface)
