  • Interface circuit for video signal peaking control
    Patent number: 4635118
    Abstract: A DC coupled system for automatically controlling the peaking content of a video signal includes a frequency selective peaking amplifier, a source of control voltage for controlling the conduction of the amplifier, and an interface circuit including a high output impedance current source network for coupling the control voltage to the amplifier. The interface circuit prevents the amplifier from being loaded excessively by the impedance of the source of control voltage, and assists to assure that the amplifier exhibits negligible gain for DC conditions.
