CONVERTER OF SHAFT ROTATION ANGLE INTO CODE Russian patent published in 2009 - IPC H03M1/58 

FIELD: physics, controls.

SUBSTANCE: invention concerns automation and computation. Effect of invention is achieved by converter including first alternate voltage source connected to one of input coils of angle sensor and to first inputs of first and second simultaneous detectors, second inputs of which are connected to first and second outputs of angle sensor respectively, while outputs are connected over first and second keys to data input of analog-to-digital converter with output connected to data inputs of first, second and third registers; output of first register is connected to computation unit, while outputs of second and third registers are connected to computation unit over averaging adder; control signal generator with outputs connected to control inputs of first and second keys, first, second and third registers, adder, analog-to-digital converter, computation unit and second control input of first register. Additionally converter features second alternate voltage source, third and fourth simultaneous detectors, third and fourth keys, so that second source is connected to second input coil of angle sensor and to third and fourth simultaneous detectors, second inputs of which are connected to first and second outputs of angle sensor and outputs are connected over third and fourth keys to analog-to-digital converter; and additional outputs of control signal generator are connected to control inputs of third and fourth keys.

EFFECT: enhanced accuracy of angle-to-code conversion.
