求系统串联滞后校正器传递函数的函数 ，其中sope是系统的开环传递函数，当key=1时，var为gama，是根据要求校正后的相角 稳定裕度计算之后校正器；当key=2时，var=wc，则是 根据要求校正后的剪切频率计算校正器。(Demand system is connected lag compensator transfer function of the function, which sope is the system open-loop transfer function, when key = 1 时, var is gama, is adjusted according to the phase angle required stability margin calculation after corrector when key = 2, var = wc, is the required shear frequencies after correction corrector.)

I have thoroughly study the basic of image compression techniques. From that I have selected SPIHT algorithm for my research work. I have implemented on image compression for gray images using SPIHT algorithm. Image compression is implemented using this algorithm has better result over the previous result on gray images and also improved PSNR value high but on other side low result on compression ratio.
