摘要：
A reverse feedback amplifier which generates a correction current having two oscillations per line period is used to eliminate geometric distortions on the screen on a television kinescope. The reverse feedback amplifier includes an output transistor, a resonance transformer and a feedback network. An improvement of the amplifier includes a switch and a resistor for decreasing the output voltage of the reverse feedback amplifier during the scanning of the center portion of the screen.
