摘要： A digital phase locked loop includes a phase acquisition unit receiving a sampled input signal and applying its output to a first input of a digital phase detector, a digital controlled oscillator producing a digital output, and a feedback path coupling the digital output of the digital controlled oscillator to a second input of the digital phase detector in the digital domain. The input signal may be sampled asynchronously.

摘要： An inertial sensor is described that has a commanded test function. The sensor is of a ring type driven by a driver circuit, the sensor further includes primary and secondary portions having corresponding signal pickoffs. The primary pickoff signal amplitude is controlled via an automatic gain control, the primary phase lock loop and VCO locks to the resonant frequency to provide the clocks for the synchronous detectors, the primary pickoff signals via the primary phase shift circuit is provided to the primary driver, the secondary pickoff signal being input into a detector circuit capable of detecting motion in the sensor. The commanded test function includes a signal derived from the primary portion of the circuit and input into the two inputs of a differential amplifier in the secondary pickoff detector circuit.
