LOW COST MONITOR FILTERS
TFV SERIES
These low cost luma and chroma anti-aliasing and reconstruction filters, are designed for use in 4:2:2 a-d
and d-a conversion i.e. sampling rates of 13.5 MHz (Y channel) and 6.75 MHz (U and V channels). Pre-
filters have a flat passband and the post-filters are shaped to provide sinx/x correction. These filters provide
similar performance to the Faraday TFT range but at much reduced cost.
