The main objective of this paper is to create a novel approach for synthesizing multi-channel sine wave and square wave. In several kinds of equipment, it is essential to produce the accurate waveforms under various frequencies and profiles such as agile frequency source. Also it should have low phase noise, low spurious signal content for communication in various applications. Direct Digital Synthesizer...
An enhanced decision based algorithm for the removal of high density salt and pepper noise with reduced streaking is proposed. A fixed 3×3 window is kept constant for the increasing noise densities. The processed pixel detects salt and pepper noise using the max-min pixel value of the current processing window. If the processed pixel lies between both maximum and minimum value then the processed pixel...
