As shown in (5), the inductor current oscillates around
a
dc value at twice the grid frequency. The PWM
technique assumes a constant dc input current and thus,

DCTJPEG
使用Matlab编程实现发送端信源编码(图像压缩)和接收端信源解码(图像重建),其中的编解码算法可采用基于DCT变换的JPEG图像压缩标准;测试图像加噪,然后对去噪后的图像进行压缩与重建,分析压缩性能;研究基于下采样和内插的图像压缩算法;可将8bit/pixel灰度图像扩展至24bit/pixel彩色图像,或者采用无损压缩算法对图像压缩。(Sender using the Matlab programming source coding (image compression) and the receiver source decoding (image reconstruction), one of the decoding algorithm can be used DCT-based JPEG image compression standard test image with noise, then the denoised image compression and reconstruction, compression performance analysis of down-sampling and interpolation based on image compression algorithm 8bit/pixel grayscale images can be extended to 24bit/pixel color images, or the use of lossless compression algorithms for image compression.

jpeg_encode+decoderhojoon
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.
