使用matlab编写的合成地震记录 里面注释很全的，看看吧，会有用的(synthetic seismogram matlab)

基于MATLAB高通低通滤波器源程序,很详细的源程序，有注释的哦！(good and Strong！you will like it!if you fell good ,please support me!)

LMS ALGORITHM CODE TO SUPPRESSION ECHO

本代码可不用借助其他工具直接对光子晶体光纤的色散等直接计算，对学习pcf的朋友很有帮助！(This code can be without the help of other tools directly on the photonic crystal fiber dispersion and other direct calculation, learning pcf helpful friends!)

该程序给出了基于AR时间序列建模的陀螺随机漂移模型，并利用卡尔曼滤波方法滤除陀螺随机漂移，经验证，有良好效果。(failed to translate)

A 4 bit twisted ring counter is a sequential circuit which produces the following sequence of output values: 0000, 1000, 1100, 1110, 1111, 0111, 0011, 0001 and then repeats. Design a circuit for a 4 bit twisted ring counter that uses four D flip flops. Draw a state transition diagram, a state table and a schematic for your circuit. Design an alternate implementation using just three flip flops and draw a state transition diagram, state table and a schematic for your circuit. If your designs are extended to implement an n bit twisted ring counter, how many flip flops are required using each of the two approaches. In what situations would you prefer the first method? In what situations would you prefer the second?
