Abstract :
In order to meet the performance of realtime system, multirate digital signal processing is discussed in frequency spectrum, then a polyphase structure based efficient implementation scheme of the fractional sampling rate converter is presented. Applying the converter to image scaling, the simulation results show that the margin of the output image is legible, demonstrating the validity of the proposed fractional polyphase converter.
