Abstract

A physical quantity measuring method includes: (a) generating a synchronized input signal from an input signal, wherein the synchronized input signal is synchronized with a preference clock; (b) measuring a total number (N sum ) that is the sum of pulses of the reference clock included in each of units of the synchronized input signal; (c) generating 2n deviation signals based on a delay of the synchronized input signal with respect to the input signal; (d) generating a deviation integration signal by subtracting the total values of n rear-half deviation signals from the total values of n front-half deviation signals; (e) converting the deviation integration signal into a number of pulses of the reference clock; and (f) calculating the average number (Nr ave ) of pulses of the reference clock included in one unit of the input signal, based on the total number (N sum ), the number (dN sum ), and the number n.
