摘要：
A device that provides the independent wide-range luminance and contrast control of a composite video signal is reported. The operation range of the luminance signal is 0-2 V. The range of the image contrast control is 0-50 dB. The inherent noise referred to the input is 0.1 mV. The input and output impedances are 75 Omega. The temperature stability of the clipped signal is 0.05 mV/degrees C.
