PURPOSE:To make design changes on an apparatus side and a synchro-receiver on the apparatus side unnecessary even when the sort of a gyroscope is changed by converting to the desired form for output a synchronizing signal outputted from the transmitting part of a gyro device by a wave converting circuit. CONSTITUTION:A wave converting circuit 8 is outputted converting each three- phase voltage (R, S, T) with respect to a voltage V into a desired form (for instance a square pulse) S1, S2, S3, when an alternating three-phase voltage from a synchro-transmitter and a reference voltage V as a basis are inputted. A latch circuit 9 maintains the condition of the signals S1-S3 and supplies signals, S1'- S3' to a signal processing circuit 10, when a starting signal 6 is impressed. A circuit 10 consisting of a ROM for instance, judges the phase order of the signals S1-S3 with respect to the signals S1'-S3' whether in a forward direction or reverse direction, and an up pulse S4 or a down pulse S5 are outputted, and synchronizing with it, a signal S6 is outputted to the circuit 9. Accordingly even when the sort of signals and the voltage values are changed by the sort of the gyro device, the pulse S4 or S5 corresponding to the input value is outputted and the control of the succeeding device can be performed. |
