Abstract
A coring circuit located prior to the aperture corrector circuit provides fast acting, remotely controlled, temperature compensated, frequency selective coring of the video signal. The wideband video signal is separated into its low frequency and high frequency components. The high frequency component is transformer coupled to a coring means proper which cores out the corresponding high frequency noise. The cored high frequency component then is recombined with the low frequency component to reconstitute the cored composite video signal for subsequent application to the aperture correction circuit.
