However, this selector has insufficient selection accuracy and allows false alarms if there are interference of equal duration for the selected pulse at the input.

Claims

The selector works as follows. The reference impulses are constantly received by the input of the imager 1, from the outputs of which the pulses corresponding to their anterior, froths, go to element 3, and the pulses corresponding to the rear, I to element 5 and disjunctor 6. The selectable impulse enters the input of the imager 2, sec exits; where the pulse corresponding to the leading edge is fed to element 3, and the pulse corresponding to the falling edge is sent to element 5. When the pulses corresponding to the leading edges, supporting the selected pulses, coincide, the output of element 3 appears at the output of element 3 4 Similarly, when pulses coincide at the inputs of element 5 and if there is a resolving potential at the third input from trigger 4, the output of element 5 appears a pulse indicating that the selectable and reference pulses are equal and coincide their phase. The return of the selector to the initial state is effected by a pulse from the disjunctor 6, an impedance line 7. The appearance of an impulse of interference, equal in duration to the selectable pulse, does not cause the selector ring to be selected because it does not coincide in phase with the reference signal. Claims of the Pulse Selector in duration and phase, containing two pulse formers, two coincidence elements and a delay line, characterized in that, in order to eliminate false alarms and improve the selection accuracy, a trigger trigger and a speaker are introduced, one of the inputs which is connected to the output of the first driver connected via the second element of coincidence with another input of the disjunctor, whose output through the delay line is connected to one of the inputs of the memory trigger, the output of which is connected one of the inputs of the second coincidence element, one output of the second form being compressed through the first match element connected to another input of the memory trigger, with one of the inputs of the first driver, and the other output of the second driver connected to one of the disjunctor inputs. .
