Integrated filter for video color processing
Abstract
Besides some analog integrated circuits, the PAL color decoder of a color TV set consists of various filters. Some of them can be integrated with modern semiconductor technologies. The advantages are a reduction in costs and adjustment and an increased reliability and performance. A concept was developed which uses CCD filters for the PAL-comb-filter, the luminance- delay-line and the color trap. These filters were fabricated and their performance was proved by measurement and by simulation with video signals. A PAL-video-IC, which includes the demodulation, amplifying, matrix and controlling was designed. It is matched to the CCD-filters.
