A circuit for directional orientation controlled by two pulse trains with phase shift composed of known elements of digital electronics e.g. inverters /NAND logical gates/ and D-flip-flops - containing the first inverter in one line, whose inputs are connected with the input of the write enable of the first flip-flop in this line and to the input of the data-in of the first flip-flop in the second line, and the control inputs of the first inverter in the second line are connected with the input of write enable of the first flip-flop in the second line and the input of the data-in of the first flip-flop in the first line and the signalling output of the first inverter in this line is connected to the input of write enable of the second flip-flop in the first line and the input of data-in of the second flip-flop in the second line and the signalling ouput of the first inverter in the second line is connected to the input of write enable of the second flip-flop in this line and the input of data-in of the second flip-flop in the first line characterised in that signalling inverting input (Q) of the first flip-flop (3) in the first line (B) is connected to the blocking input (R) of the first flip-flop (4) in the second line (A), and the signalling inversing output (Q) of this flip-flop (4) is connected with the blocking input (R ) of the first flip-flop (3) in the first line (B), and the direct signalling input (Q) of this flip-flop (3) in the first line (B) is connected with the blocking input (R) of the second flip-flop (9) in the first line (B) via one of the inputs of inverters (5, 7) connected tandem, and in turn, the direct signalling output (Q) of the first flip-flop (4) in the second line (A)....<IMAGE>
