经典图像边缘检测(微分法思想)——Roberts微分交叉算子 优点：模板小，计算量小；(Classic edge detection (differential method thought)- Roberts differential crossover advantages: template small, small amount of calculation )

Solving using an efficient algorithm for tridiagonal matrices TDMA Reynolds equation is solved fast and simple.

1.录制一段自己的语音信号,对录制的信号进行采样 画出采样后语音信号的时域波形和频谱图 给定滤波器的性能指标,采matlab设计数字滤波器,并画出滤波器的频率响应 然后用自己设计的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 回放语音信号。2.(1. Recorded his voice for some signal, the signal is sampled on the record draw sampled speech signal time-domain waveform and frequency spectrum performance for a given filter, mining matlab digital filter design, and draw the filter frequency response then use their own filters designed to filter the collected signals, to draw the filtered time domain waveform and frequency spectrum, and comparing the signal before and after filtering, analysis of signal changes playback of audio signals. 2.)

实现了小波变换的阈值去噪算法，并实验仿真对比去噪效果(Internship wavelet threshold de-noising algorithm,)

这是一基于MATLAB的复调制ZOOM-FFT的研究和实现的一篇文章，为的是提高频率分辨率。(This is a MATLAB-based complex modulation ZOOM- FFT Research and Implementation of an article, To improve the frequency resolution.)
