Resistor-matched deflection apparatus for a video display

摘要

In a D.C. coupled vertical deflection circuit, an input sawtooth signal is coupled to an inverting input of a vertical deflection amplifier via a first resistor network. A D.C. voltage is coupled to a second input of the amplifier via a second resistor network for preventing the D.C. signal component from affecting the deflection current. To provide temperature compensation, for every resistor included in the first resistor network, there is included a corresponding resistor of equal value in the second resistor network.
