Abstract:
Even if the propagation time interval of a sync signal is not constant, an accurate correction parameter is calculated, so that a corrected time point synchronized with a main clock device is obtained. A main transmission time point storage part stores respective main transmission time points at which a main device has transmitted a plurality of main sync signals and which are measured using a main clock device. A subordinate reception time point storage part stores respective subordinate reception time points at which a subordinate device has received the plurality of main sync signals and which are measured using a subordinate clock device. A speed ratio calculation part calculates a speed ratio of a ticking time speed of the main clock device to a ticking time speed of the subordinate clock device, based on a main transmission mean time point being a mean of the main transmission time points and a subordinate reception mean time point being a mean of the subordinate reception time points.

Claim (Index 3):
The subordinate device according to  claim 2 , wherein the speed ratio calculation circuitry includes:\n main transmission time point difference calculation circuitry that calculates a main transmission time point difference obtained by subtracting, from a first main transmission mean time point being a mean of a plurality of main transmission time points stored by the main transmission time point memory for a plurality of main sync signals belonging to a first group out of the plurality of main sync signals, a second main transmission mean time point being a mean of a plurality of main transmission time points stored by the main transmission time point memory for a plurality of main sync signals belonging to a second group which is different from the first group out of the plurality of main sync signals, subordinate reception time point difference calculation circuitry that calculates a subordinate reception time point difference obtained by subtracting, from a first subordinate reception mean time point being a mean of a plurality of subordinate reception time points stored by the subordinate reception time point memory for the plurality of main sync signals belonging to the first group, a second subordinate reception mean time point being a mean of a plurality of subordinate reception time points stored by the subordinate reception time point memory for the plurality of main sync signals belonging to the second group, and quotient calculation circuitry that calculates the speed ratio, by calculating a quotient which is obtained by dividing the main transmission time point difference by the subordinate reception time point difference.
