ANGLE-TO-DIGITAL CONVERTER Russian patent published in 2014 - IPC H03M1/00 

FIELD: instrumentation.

SUBSTANCE: angle-to-digital converter comprises: a pseudorandom code scale with information track, n information reader elements, k correction reader elements, n modulo-two adders for two inputs, the outputs of n reader elements are connected to the first inputs of n modulo-two adders for two inputs, k modulo-two adders, the outputs of k correction reader elements are connected to the first inputs of k modulo-two adders, the outputs of m reader elements are connected to the corresponding inputs of the i^th modulo-two adder, a decoder, the i^th input of which is connected to the output of the i^th modulo-two adder, the j^th output of which is connected to the second input of the corresponding modulo-two adder for two inputs, the outputs of which are the information outputs of the converter, the modulo-two adder, (n+k+1) inputs of which are connected to the outputs of n reader elements, the outputs of k correction reader elements and the output of controlling reader element, the OR-NOT element, which first input is connected to the output (n+k+1) of the input of the modulo-two adder, and the second input is connected to the zero output of the decoder, which j^th outputs and the output of the OR-NOT element are service outputs of the converter.

EFFECT: improving information reliability of the angle-to-digital converter.
