AUTOMATIC LUMINANCE CHANNEL BANDWIDTH CONTROL APPARATUS RESPONSIVE TO THE AMPLITUDE OF COLOR IMAGE INFORMATION Abstract of the INVENTION In a television signal processing system, including separate channels for processing luminance and chrominance signal portions of a composite video signal, apparatus is provided for automatically varying the bandwidth of the luminance channel in accordance with the amplitude of color information signals. In an illustrated arrangement, apparatus for controlling the bandwidth of the luminance channel is coupled to a color demodulator circuit which is included in the chrominance channel for generating, for example, R-Y, G-Y and B-Y color difference signals. The bandwidth of the luminance channel is controlled to vary in inverse relation- ship to the amplitude of the demodulated color difference signal having the largest amplitude. -1-
