Patent ID: 7330803

Claim:
A time interval measurement apparatus comprising: a single signal channel carrying an initial signal and a plurality of time spaced subsequent signals; means for generating a continuous stream of full clock time periods, each having a set clock time; a single counter, the counter counting a total number of full clock time periods between the initial signal and each one of the subsequent signals; single means for generating a first clock fractional time period starting from the initial signal and the start of the next clock time period, and a second clock fractional period between each one of the subsequent signals, and the start of the next respective clock time period; single means for combining the first and second clock fractional periods and the total number of clock time periods to generate the total time intervals between the initial signal and each one of the subsequent signals; and the single counter, the single means for generating clock fractional time periods, and the single means for combining defining a single measurement channel for measuring the time intervals between the initial signal and each of the plurality of subsequent signals.
