This paper presents a kind of algorithm which is used to calculate axial angle through the a- nalysis of the output signal characteristics of synchro or resolver. Based on this algorithm is the design for the axial angle acquisition circuit including signal isolation AD conversion, axial angle calculation and digital signal output. By using the circuit, it is possible to succeed in conducting the high-preci- sion axial angle analog-digital conversion of synchro and resolver. The method is proved to be feasible in practical application.
