Pronynalysis
Prony分析是获取系统振荡模式特征的一种非常有效的方法,它可以通过给定输入信号下的响应直接估计系统的振荡频率、衰减、幅值和初相位。本文基于Prony算法提出一种用振荡模式能量级鉴别电力系统大干扰下主导低频振荡模式的方法。(Prony analysis acquisition system oscillation mode features a very effective way, It can set the input signal to the estimated direct response to the oscillation frequency, attenuation, amplitude and phase. Based on Prony algorithm proposed by the energy level oscillation mode differential interference large power systems under low-frequency oscillation mode lead style approach.)

This is a JPEG encoding & decoding program of still image. It does not use level shifting. Discrete Cosine transform (DCT) is performed both by classical & Chen s Flowgraph methods. Predefined JPEG quantization array & zigzag order are used here. RUN - LEVEL coding is used instead of Huffman coding. Compression ratio is compared for each DCT method. Effect of coarse and fine quantization is also examined. The execution time of 2 DCT methods is also checked. In addition, most energatic DCT coefficients are also applied to examine the effect in MatLab 7.4.0 R2007a. Input is 9 gray scale pictures & output is 9*9=81 pictures to compare. Blocking effect is obvious.
