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 4):
The subordinate device according to  claim 2 , wherein the correction parameter calculation device further comprises:\n a subordinate transmission time point memory that stores subordinate transmission time points at which the subordinate device has transmitted a plurality of subordinate sync signals and which are measured using the subordinate clock; and a main reception time point memory that stores main reception time points at which the main device has received the plurality of subordinate sync signals and which are measured using the main clock, wherein: m t =main transmission mean time point, m r =main reception mean time point, s t =subordinate transmission mean time point, s r =subordinate reception mean time point, the speed ratio calculation circuitry includes: product difference calculation circuitry that calculates a transmission/reception time point product difference\n \u0394 ms = m t s r \u2212 m t s r + s t m r \u2212 s t m r , \n square difference calculation circuitry that calculates a subordinate time point square difference\n \u0394 s 2 = s r 2 \u2212 s r 2 + s t 2 \u2212 s t 2 , and \n quotient calculation circuitry that calculates the speed ratio=\u0394ms/\u0394s 2 .
