PURPOSE:To improve the reliability in a selection circuit which selects the phase shift signals from resolver phase shifters optionally by providing said circuit and processing the correction of the deviation in the synchronization between the resolver phase shifters in a microprocessor. CONSTITUTION:A selection circuit 23 selects the phase shift signals 11a, 11b of resolver phase shifters 1a, 1b optionally, selects the respective amplified signals 13a, 13b of the signals 11a, 11b with a selection signal 24 and outputs the same to a Schmitt circuit 14. A microprocessor 22 applies the signal 24 to the circuit 23, is inputted with an excitation signal 8 to load the content of a storage circuit 19 therein and corrects the deviation in synchronization. |
