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.

A_Millimeter-Wave_Circuit_Technique
An inductive feedback technique increases the speed
of resonant circuits by 62 , allowing operation near the of
transistors. The technique leads to a fundamental oscillator operating
at 128 GHz with a power dissipation of 9 mW and a phase
noise of 105 dBc/Hz at 10-MHz offset. A divide-by-two circuit
based on the idea and incorporating a sampling mixer achieves a
maximum speed of 125 GHz while consuming 10.5 mW. The prototypes
have been fabricated in 90-nm CMOS technology.(An inductive feedback technique increases the speed of resonant circuits by 62 , allowing operation near the of transistors.
