ABSTRACT:
A system and method for generating an approximated position signal that is updated and output at a rate higher than a base rate of actual position signals measured using a position transducer. The actual position signals are determined and/or stored by a transducer signal processing circuit at discrete time intervals. The approximated position signals are generated by a high frequency estimated position generating circuit. A rate of incrementing the approximated position signals is adjusted for use during the next discrete time interval by an error correction feedback loop, based on a difference between certain approximated and actual position values. The accuracy of the system may be further improved by utilizing a latch signal to ensure that the approximated and actual position values that are compared by the error feedback loop correspond to the same time.
