FIELD: automation and computer engineering; controlling angular position of moving parts in pieces of equipment under control.
SUBSTANCE: proposed digital converter that has real two-phase angle transducers whose output voltage envelopes may be other than orthogonal, may have different amplitude values, and may incorporate third, fifth, seventh, and ninth spatial harmonics of this or that magnitude is provided with newly introduced respective correction circuits including adjustable voltage dividers for shaping signals correcting conversion error components of sine4α and sine8α kind, where α is angular position of two-phase angle transducer rotor.
EFFECT: enhanced precision of angle-to-code conversion.
