SAA7152 Description
The CMOS digital b filter circuit is located between video analog-to-digital converters and the video multistandard decoder SAA7151B (not applicable for SAA7191B). The two-dimensional filtering is only appropriate for standard signals from a source with constant phase relationship between subcarrier signal and horizontal frequency. The b-filter has to be switched off for VTR-signals and for separate VBS and C...
