Abstract
A time interval measuring system includes circuitry for generating a signal indicating the beginning and end of a time interval, a clock to generate a periodically increasing clock signal, and a counter to count the clock signal between the beginning and end of the interval. The periodically increasing clock signal comprises a series of pulses each of which has a pulse period which is longer than the pulse period of the preceding pulse by a predetermined ratio greater than one.
