Claims

The pulse comparison device comprises a pulse generator 1 with an output pulse transformer 2, an input cascade 3 comprising a transistor 4, diodes 5 and 6 and resistors 7 and 8, a first switching device on a tunnel diode 9 and a transistor 1O, a second switching device on a tunnel diode 11 and the transistor 12, the clock device on the tunnel diode 13 and the transistor 14 and the trigger device on the thyristors 15 and -16 with effective healing transformers 17 and 18, and the signal from the secondary winding of the pulse transformer 2 is connected between the plus power supply and cathode of diode 5, the anode of which is connected to the anode of diode 6, the cathode of which is connected through the resistor 7 to the minus of the power supply, and to the transistor 4 set, the base of which through the resistor 8 is connected to input 19 first to second switching devices. The second secondary winding of the transformer 2 is connected to the output of the first switching device and the input of the clock device, the output of which through the transformer 17 no.t is connected to the control R, the thyristor 15, and the output of the second switching device through the transformer 18 k to the control electrolyte of the thyristor 16, the anode of which is connected through a capacitor to the anode of the thyristor 15 and is the output of the comparison device. The device works as follows. If there is no signal at input 19, transistor 4 is closed and no impulses are present at the input of the first and second switching devices. From the secondary winding of the transformer 2, pulses continuously flow into the input of the clock device, from which it operates and outputs control signals through the transformer 17 to the input of the thyristor 15, which opens and the trigger goes into one of the stable states. When a control voltage is applied to the input 19, the transistor 4 opens slightly and the inputs of the first and second switching devices receive pulses whose amplitude is determined by the value of the control voltage. When the pulses reach an amplitude equal to or greater than the response level of the first switching device, it exhausts the inhibit pulses on the clock device, which stops the latter from starting from the generator 1. The trigger device continues to remain in its original position. When the amplitude of the pulses at the emitter of the transceiver 4 of 4 is triggered by the second threshold device, the latter pulses through the transformer 18 to switch the trigger to another stable state.
