Abstract

Six parallel ring memory shift registers have their data inputs connected to input switches which are in turn connected to the output of an analogue-digital converter. The shift register outputs are connected to output switches connected in turn to the input of a digital-analogue convertor. Each first shift register data input is connected to the register output through a feedback and the shift timing inputs are connected to input to an angle gauge also connected to the input of a difference forming unit. The second input of the latter is connected to the input to a second angle gauge, and its output is connected to the input switches and the output switches.
