DIGITAL ANGLE CONVERTER Russian patent published in 2007 - IPC H03M1/48 

FIELD: automatics and computer engineering, possible use in systems for controlling angular position of moving parts of control object.

SUBSTANCE: in accordance to the invention, current error of conversion is determined as constant current voltage, which is converted in analog-digital manner to appropriate array of correction codes supported by output code of digital angle converter, also provided is operative storage of resulting array in random-access memory device, following long-term storage in programmable memory device and its usage for digital-analog generation of voltage for correcting current conversion error.

EFFECT: ensured precise transformation of angle to tracking type code with usage of two-phased angle sensor with dependencies, corresponding to functions of type and where α - angular position of rotor of two-phased angle indicator.
