Patent abstract
A force-balance accelerometer having a pick-off coil responsive to displacement of a seismic mass from a balance position for providing an output corresponding to the displacement, includes a digital signal processor including tow pulse width modulation generators for converting the output of the pick-up coil to a digital signal, and a torque coil responsive to the digital signal for rebalancing the seismic mass by restoring the mass to the balance position. The processor outputs the digital signal as first and second PWM signals, which control the digital signal.
