ABSTRACT:
A time of an event can be determined by acquiring an amplitude, at the time of the event, of at least two periodic timing signals that are out of phase with each other. The time of the event within a cycle of at least one of the timing signals can be determined as a function of the amplitudes of the timing signals. The phase angle and complex coordinates of at least one of the timing signals can be determined as a function of the amplitudes. The time of the event within a cycle of a timing signal can be determined as a function of the phase angle or complex coordinates of the timing signal at the time of the event.
