Sub-carrier rejection filters are notch filters designed to remove the 3.58 MHz sub-carrier from NTFC color signals. Most applications for this type of filter are based upon rejection of the color information in the video signal to provide isolation from the luminance signal. This application requires low phase distortion to the luminance signal. To satisfy this requirement, we have designed the VFR series of filters. One of the most often used applications for this filter is in color systems for monochrome transmissions to prevent color flashes from appearing on the screen. Since various segments of the television industry have different bandpass requirements, filters of different bandwidth are offered. Where required, phase correction is included. The photographs of the 20T pulse show the reduced picture definition the wider the bandwidth.
