Abstract : The patent describes a servo system using an electronic chopper for producing shaft rotation indicative of the amplitude of a DC input signal. The DC signal is converted to square wave form by shunting the signal through a complementary pair of transistors to ground. A constant AC signal applied to the input bases of the transistors determines the frequency of the shunting action which in turn determines the frequency of the square wave. The square wave signal is amplified and applied to a servo motor for driving a potentiometer indicator in accordance with the amplitude of the DC input signal.
