ABSTRACT:
The output of the accelerometer is sent to a pulse width modulating digitng circuitry which consists of a comparator to generate the PWM signal, a flip-flop steering circuit, an "H" switch to toggle the torquer constant current either positive or negative, and an AND gate to gate the clock pulses for the output.
