PURPOSE:To contrive to increase a receiving processing speed, by utilizing the same sampling data in the coincidence judgement of the repeating cycle of a pulse line signal and each set repeating cycle. CONSTITUTION:The sampling data of a pulse line signal repeated at a predetermined cycle is stored in a sampling data storing means (a) and a plurality of pulse line signal repeating cycles are set to a repeating cycle setting means (b). The stored sampling data is divided by a set repeating cycle in a sampling data dividing means (c) and the divided sample data are synchronously added by a synchronous adding means (d) and, in a cycle coincidence judge means (e), the coincidence of the repeating cycle of the pulse line signal and the dividing set repeating cycle is further judged from the pattern of the synchronous added data. By this method, because the same sampling data is utilized in the concidence judgement of a cycle, the increase in the speed of receiving processing operation is enabled. |
