about with

The invention relates to automation and pulse technology and can be used in software and temporary devices.

The aim of the invention is to reduce hardware costs.

The goal is achieved by eliminating from the structure of the device such complex nodes as an adder and two multi-bit comparison circuits.

The drawing shows a functional diagram of the device.

The device contains a pulse generator 1, a control trigger 2, a switch block 3, an element OR 4, a pulse shaper 5, a pulse counter 6, which forms a trigger 7, a pulse shaper 8, buses: input 9, reset 10, duration code 11, delay code 12 , output 13.

The pulse input of the pulse counter 6 is connected to the output of the pulse generator 1, the control input is connected to the output of the element OR 4, the information inputs are connected to the outputs of the switch block 3, and the output is connected to the input of the forming trigger 7. The information inputs of the switch block 3 are connected to the buses P and 12, and the control input to the output of the forming trigger 7, output bus 13 and through the pulse shaper 5 to the input of the element OR 4. The output of the control trigger 2 is connected to another input of the element OR 4, and the first and second inputs to the bus 9 and bus 10. Output forma Through the pulse shaper 2, the trigger trigger 7 is connected to the third input of the control trigger 2.

The device works as follows.

The signal arriving at the resetting bump 10, the device is reset. From the output of the control trigger 2, the control input of the counter 6 receives the level at which the code set at its information inputs is written to the counter 6 and the counting of the input pulses is inhibited. At this time, from the output of the shaping trigger 7, the switches of the switch block 3 are set to the code of the control inputs of counter 6 receive a code from the delay code 12 bus. Thus, a number corresponding to the output pulse delay time is entered into counter 6. When a delayed pulse arrives at the input bus 9, the control trigger 2 overturns and a level arrives at the control input of the counter enabling the pulse generator 1 pulse counting (counter 6 operates in the subtraction mode).

When counter 6 is set to the zero state, a signal appears at its output, overturning the forming trigger 7. On the output bus 13

the leading edge of the output pulse is formed. In this case, the switches of the switch block 3 are connected to the information inputs of the counter 6, a code bus of duration 11, and the output

pulse generator 5 a short pulse is generated, during the operation of which a code corresponding to the output pulse duration is written to counter 6. Then the number written to counter 6 is read again by pulses of the pulse generator 1.

When a signal appears at the output of the counter 6, the forming trigger 7 again

topples over. On the output bus 13, a falling edge of the output pulse is formed. In this case, a short pulse is formed at the output of the pulse generator 8, which overturns the control trigger 2. At the control input of the counter 6, a level is set that prohibits the counting of pulses of the pulse generator 1 and resolves the 1st entry of the delay code.

The device is ready for the next cycle of operation.
