PURPOSE:To obtain a correct time count output with the correction of time errors due to turbulence by transmitting or receiving data by wireless to count time. CONSTITUTION:When the third data is received normally, (010) is latched as counting data into a latch circuit of a circuit 25 and supplied to an arithmetic circuit 26. An output is fed to an FF circuit 30 through a gate circuit 33 from the FF circuit identical to an FF circuit 21 of a circuit 16 to reset it 30. The counting of time ends and the output of the circuit 26 is subtracted from the contents of time counts of a memory circuit 27. The computation of (Y-X) is performed with the circuit 26. With an arithmetic circuit 28, the results '1' of the computation is subtracted from the contents of time counts of the circuit 27 and the results are shown on a display 29. In this manner, time errors in the receiving of data is corrected and a correct time counted is displayed. |
