【Abstract】 This Paper introduces principles of high - accuracy - rate system based on phase difference to voltage converting and realization of hardware circuit,it also goes into details on the keytechniques of each part. The experimental adjustment work demonstrates that this scheme is easily-realized,and has high reliability in addition,it overcomes some defects in increment-encoding-rate system by using lockingphase circuit.更多还原
