GFG SERIES
ANTIALIASING FILTERS
These very small, low cost, filters are intended for use with A-D and D-A video converters where
some deviation from full multicodec standards is allowed. The cut off rate is slower than
recommended to reduce time domain ringing.
The filters are designed for use in systems adhering to the EBU standard for 4:2:2 A-D and D-A
conversion i.e. sampling rates of 13.5 MHz for the luminance (Y) channel and 6.75 MHz for the
chrominance (U and V) channels. The pre-filters have a flat passband and the post-filters are shaped
to provide sinx/x correction. Filters suitable for different sampling rates or with various losses at the
half sampling frequency can be supplied.
