Abstract
A circuit apparatus for providing increased apparent resolution in digital signal processing systems includes a comparison circuit receiving an N bit digital input signal and the N most significant bits of an N+M bit output signal. The comparison circuit compares the two signals and provides a control output in response to the comparison. An N+M bit counter increases or decreases a count value which is the output signal in response to the comparison, whereby the output signal has an apparent resolution 2.sup.M better than the resolution of the input signal.
