COMPOSITE VIDEO COLOUR
SUB-CARRIER PASS AND
REJECTION FILTERS

These sub-carrier pass and rejection filters are to a proven design to suppress or pass the colour sub-carrier elements of a composite video signal. The reject filters are group delay equalised in order to minimise the distortion to the luminance signal. With this type of filter there is always a compromise between the amount of colour signal rejected and the loss of picture definition which can be tolerated.

The filters offered below have found to be acceptable but other bandwidths and rates of cut-off can be supplied upon request.
