Color Decoding
Decimation Filter
The digitized composite video data at 2X pixel clock rate first passes through decimation filter. The
decimation filter is required to achieve optimum performance and prevent high frequency
components from being aliased back into the video image. Fig2 shows the characteristic of the
decimation filter.
