ABSTRACT:
A circuit can be configured to process signals from either a resolver or an encoder to derive an indication of the sensed angular position. (1) When the circuit is configured for an encoder, the output from the encoder is periodically sampled. The phase relationship of the encoder input signals controls a counter. The output of the counter is periodically sampled to provide the position indication. (2) In the resolver configuration, the counter is rest at regular intervals. An apparatus detects zero crossings from the resolver signal and in response thereto samples the counter output to provide a measurement of the time interval between the counter reset and the zero crossing. The magnitude of the time interval corresponds to the phase angle of the resolver signal and hence to the angular position.
