Abstract
A technique of processing an input signal having an input signal phase is disclosed. The technique includes determining a number of transitions of the input signal within a period having a start and an end. The technique includes determining a relative beginning phase of the input signal at the start of the period, which includes generating a first reference signal having a first reference signal frequency and a first reference signal phase synchronized with the start of the period, and detecting a first time interval required for the input signal phase to have a first specified relationship to the first reference signal phase. The technique includes similarly determining a relative ending phase of the input signal at the end of the period. The technique includes determining an input signal temporal characteristic from the number of transitions and the relative beginning phase and the relative ending phase.
