Abstract
A time interval measurement apparatus and method counts the total number of full clock time periods between two measurement signals. Clock fractional time periods are generated between each of the two measurement signals and the next leading edge of a full clock time period. The total number of full clock time periods and the clock fractional time periods are converted to a time equivalent measurement and combined to generate the total time interval between the two measurement signals.
