PURPOSE:To prevent the generation of coordinates strain by making the resolving powers of respective components same, by constituting the analogue circuit parts of a synchronous rectifier and an integrator as one set while time sharing the same to take out the x-component and the y-component of unbalanced signal voltage. CONSTITUTION:The readings of a first and a second memory circuits 13', 14' are respectively controlled by opening and closing switches S1, S2 and the outputs of the memory circuits are fed back to an integator 12' through inverters 25, 26 and switches S3, S4 are respectively performed by signals R, S, T, W and switches 8', 15' are similary controlled by signals M, Q and the integrated results are read in the memory circuits by the switches S1, S2. The switch 15' is closed directly before the initiation of synchronous rectification of each component is started and the output of the corresponding memory circuit is transmitted to the integrator 12' by the switch S3 or S4. Therefore, the integrator 12' integrates the succession of the previously rectified result and, as a result, a noise component is smoothed and approaches zero with the elapse of time to make it possible to further enhance removing effect. |
