ABSTRACT:
A device for determining with high accuracy the period and frequency of an input signal by taking into account the fractions of a clock signal that are normally ignored. A gate signal with an integral number of clock pulses is generated. Each fractional time is accurately measured by first and second integrators, and an up-down counter provides the difference between the fractional times for the final determination.
