DIGITAL ANGLE TRANSDUCER Russian patent published in 2011 - IPC H03M1/48 

FIELD: information technology.

SUBSTANCE: method is realised by introducing into a digital angle transducer corresponding correction circuits when using a conditioner for signals which correct conversion error components of the type sin4α and sin8α, where α is the angular position of the rotor of a two-phase angle sensor. During said conditioning, the base voltage used is the existing (intermediate) signals of the conditioner for the reference voltage of the type minus |U₁| and |U₂|.

EFFECT: accurate conversion of an angle to a track type code using real two-phase angle sensors, the envelope curves of output voltages of which can contain a third, fifth, seventh and ninth spatial harmonics of the same value.
