These 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.
