Claims

The functional scheme of the proposed distributor is shown in the drawing. The bit outputs of shift register 1 are connected to the outputs of the distributor. The output of the generator 3 is connected to the counting input of the trigger 4, the unit output of which is connected to the inputs of the elements 5, 6 and 7, and the zero input to the output of the element 5. The second input of the element 5 is connected to the left output of the trigger 8, and the third input with a single output of the last bit of register 1. The positions 9i and Ea denote the outputs of the two-channel four-position switch 10, and the positions lib Ib, 12,222, 13, 132, MI and 142 its inputs. The second input of the element 6 is connected to the output 9i of the switch 10, the input lli of which is connected to the output of the generator zero 15, inputs 12i and 13i - respectively to the unit and zero outputs of the last digit of the register 1, and input 14i - to the output of the generator unit 16. Output 02 non-switch 10 is connected to the second input of element 7, input Ib to the output of the generator unit 16, inputs 122 and 132 respectively to the zero and single outputs of the last bit of register 1, and input From - to the output of the generator zero 15. The output of element 6 is connected to counting trigger input 8, single out which is connected to the nerve input of the element OR 17. The second input of the element 17 is connected to the output of the element 7, and the output to the clock input of the register 1. In the first mode, the outputs 9i and 92 of the switch 10 are closed respectively with the inputs 111 and Ib. When 3 signals with frequency / and period T are generated from the generator, at the output of flip-flop 4, sigpals with frequency f / 2 and period IT are formed, which, through AND 7 and OR 17, receive the clock input of register 1 at the output. When a single distributor the logic level is triggered by the AND 5 element and the trigger 4 is set to the zero state. In this case, the pulse from the unit output of the trigger 4 through the elements AND 7 and OR 17 switches the posterior discharge of register 1 to the zero state. As a result, a single logic level with a duration T is removed from the output of the 2 "distributor. In the other three modes, the distributor operates in the same way as described above. In the second mode, the outputs 9i and 92 of the switch 10 are closed, respectively, with inputs 12 and 122. As a result, from output 2 of the distributor, a single logic level is removed with the duration of the SG. In the third mode, the outputs 9i and 92 are closed, respectively, with inputs 13i and 132, and a single logic level with a duration of 0.5T is removed from output 2p of the distributor. In the fourth mode, outputs 9i and 92 are closed, respectively, from inputs 14 and 142, with the result that a single logic level with a duration of 1.57 is removed from output 2 ".
