Abstract

The scanning amplifier for deflection coils includes a feedback loop system using a resistance. To increase the pass bankd of the amplifier, the loop also includes circuitry to suppress the effect at high frequencies of the internal capacitance (Cp) across the terminals of the coil (L). The loop circuit includes a resistance bridge (R3, R4), one of the resistances (R3) being in parallel with the coil (L) and the other being in series with the coil. The bridge has the effect of maintaining the constant voltage across the terminals of the coil in series with one of the resistance (R4) of the bridge, at high frequencies.
