0 is connected to one of the output buses of the device, and through the first resistor is connected to the power supply bus, the base of this transistor, the emitter of which is connected to the common bus, is connected in parallel to the second resistor and the first diode connected to the first output pin of the pulse element The anode of the second diode, whose cathode through a capacitor / third resistor and the third diode is connected to the base of the transistor, the power supply bus and the midpoint of the resistive voltage divider, respectively, the second output of the resistor zi is connected to the common bus. The drawing shows a schematic diagram of the impulse distributor. The device contains connected in series pulse elements 1, a resistive voltage divider connected between the common bus and bus 3 of the power supply, a communication resistor 4. Each pulse element contains a transistor 5, the first b, the second 7, the third 8 resistors, the first 9 second 10, the third 11 diodes, a capacitor 12 The input of the first, pulse element is connected to the control input 13 of the device, the collectors are connected to the output buses 1–4 by a transistor. The distributor functions as follows. In the initial state, the control input 13 of the device is disconnected on the common bus. All transistors are closed, the voltages on their bases and collectors are zero and the bus voltage 3 is the power supply, respectively. The capacitors are charged up to the voltage determined by resistive divider 2. When the control input 13 is connected to the common bus, the capacitor 12 is discharged almost to zero voltage across the circuit: diode 9, coupling resistor 4, diode 10. Discharge pulse current forms on resistor 4 a short positive voltage pulse. The distributor starts when the control input is disconnected from the common bus. In this way, the transistor 5 is turned on by the charge current of the capacitor 12. A positive output pulse is formed in the collector circuit of the transistor 5. As the capacitor 12 charges, the voltage across the cathode of diode 11 decreases. When it becomes equal to the voltage at the midpoint of divider 2, diode 11 is unlocked and the charge of capacitor -12 stops. The transistor 5 is then locked and a drop of the output pulse is formed on its collector. Positive impulse} on the output bus 14, connected to the collectors of the transistors of the second, third, etc. pulse elements are formed in a similar way. When opening transistor 5 through it, it discharges; the capacitor of the second impulse element prepares the capacitor for operation. When transistor 5 begins to close, the transistor of the second pulse element is unlocked and a positive output signal is formed on the second output bus. Due to the discharge of the capacitor of the third pulse element on the resistor 4, a positive voltage pulse is again formed, forcing the locking of the transistor 5. Connecting the second output of the communication resistor to the common bus causes the forced locking of the transistors of all the pulse elements (except for the last two J) due to or on the coupling resistor of a short-term positive voltage pulse. The consequence of a decrease in the duration of the decay of the output pulses is an increase in the speed of the device as a whole. The invention of a pulse distributor containing a resistive voltage divider, a communication resistor, and series-connected pulse elements, each of which contains a transistor, three diodes, three resistors and a capacitor, the output of the pulse element is the collector of the transistor of this element, which is directly connected to one of the output buses of the device, and through a resistor connected to the power supply bus, the base of this transistor, the emitter of which is connected to the common bus The first resistor and the first diode are connected to the first connection resistor, the input of the pulse element is the anode of the second diode, the cathode of which is connected through a capacitor, a third resistor and a third diode to the base of the transistor, the power supply bus and the midpoint of the resistive voltage divider, respectively This is due to the fact that, in order to improve speed, the second output of the communication resistor is connected to the common bus.
