The drawing shows a diagram of the proposed device.

The device contains a symbol-forming node 1, an encoder 2, a group of 3 valves, an element OR 4, a start valve 5, a start trigger 6, a poll valve 7, a generator 8, a register 9, a comparison node 10, a register 11, a memory node 12, a communication node 13, a counter 14, a decoder 15, a comparison node 16, a decoder 17, a switch 18, a display node 19 and a delay element 20,

The outputs of the symbol-forming unit are connected to the inputs of the encoder 2, the outputs of which are connected to the control inputs of the valve group 3 via the OR 4 element to the start valve 5 input. The output of the start valve 5 is connected to the pulse inputs of the valve group 3 and input 1 of the trigger trigger 6, output 1 which is connected to the control input of the opamp 7 valve. To the pulse inputs of the valves 5 and 7 are connected the output of the generator 8. The outputs of the valve group 3 are connected to the setup inputs of the trigger 9, the j outputs of which are connected to the control inputs of the comparison node 10, the second control inputs of which are connected to the outputs of the trigger register 11, to the installation inputs of which are connected the outputs of the memory node 12, to the input of which the output of the polling valve 7 is connected, the output of the comparison node 1O is connected to the input of the start trigger 6 and the starting input communication node 13. The outputs of the communication node 13 are connected to the output of the entire device. The outputs of the trigger 14 of the counter are connected to the inputs of the decoder 15, the outputs of which are connected to the inputs of the comparison node 16, the outputs of the decoder 17 are connected to the second inputs, and the output of the start switch 5 is connected to the counter input of the counter 14. The outputs Comparison node 16 is connected to the input of display unit 19, as well as to the installation inputs O of start trigger 6 and counter 14. The output of interrogation valve 7 is also connected to the input of delay element 20, the output of which is connected to input O of register 11.

The operation of the device is as follows.

When a character is received from the symbol generation node 1 through the inputs of the encoder: torus 2, the character code is generated at the output of the latter, which enters the control inputs of the valves 3 and through the OR 4 element to the input of the start valve 5. Pulse | from generator 8 through the valve start 5; set.: to state I, start trigger 6 and ohfashivaet a group of valves 3, forming a character code in register 9.

I Pulse from generator 8 through valve: interrogation 7, opened by control input OUTPUT 1 of start trigger 6, is fed to input of memory node 12. In register 11, the next character code is generated and compared on the node compared to 10 with the code stored in the register 9. When the codes of registers 9 and 11 coincide, the signal from the output of the comparison node 1O arrives at the input of the communication node 13, transmitting information from the outputs of the register 11. At the same time, the start trigger 6 is set to O.

After the end of the transmission from the outputs of the communication node 13, the registers 9, 11 and the counter 14 are set to O. The register 11 is also set to O by a signal from the delay element 20 to receive the next character. If a word of several characters is formed, their codes are sequentially recorded in register 9 and the pulse from the output of the interrogation valve 7 is fed to the input of counter 14, forming the code for the number of characters arriving at register 9. At each step, the comparison node 16 is polled.

When the state codes of the counter 14 and the switch 18, defined by the states of the decoders 15 and 17, coincide, the output of the comparison node 16 generates a signal that sets the start trigger 6 and the counter 14 to the state O.

The switch 18 is set by the operator to a position whose code is one greater than the maximum 1 number of characters.
