  • Patent number: 3944881
    Abstract: Utilization of a diode in the input of the vertical deflection drive amplifier serves to render the amplifier insensitive to power supply variation and shortens the response time of the amplifier to changes in the vertical centering circuit. In one embodiment the diode is connected in series with the variable terminal of the centering potentiometer in the input of the vertical drive amplifier. In a second embodiment, wherein the vertical deflection drive amplifier includes a differential amplifier, the diode is connected to one input of the amplifier and the centering circuit is connected to the second input of the amplifier. In both embodiments the diode forms part of a time constant circuit which controls the linearity of the sweep signal applied to the input of the amplifier and also controls the response time of the amplifier to DC voltage level change.
