Abstract

PURPOSE: To improve the resolution of the average time interval measurement by falsely continuing the phase of the oscillation at the end of time interval measurement in the frequency of m+1 and at the beginning of time interval measurement in the frequency of m.
CONSTITUTION: Upon the inputting of the start signal, a phase retaining oscillator 22 starts oscillation and the output is pulsated 23 for counting 4. Upon the inputting of the top signal, a retention signal is applied to the phase retaining oscillator 22 to stop the oscillation. Likewise, upon the end of counting 10n times, the output signal of a 1/10n divider 5 drives a mono-stable multivibrator 6 to memorize and indicate the contents of a counter 4 with a memory/display means. Then, the counter 4 and the divider 5 are reset with a mono-stable multivibrator 7, returning to the initial condition.
