FIELD: electrical engineering.
SUBSTANCE: device comprises two transistors, two collector resistors, two interstage capacitors, each being connected to collector of one transistor and base of another transistor. Flip-flop incorporates two extra transistors, two extra collector resistors and two feed resistors with extra transistors. Extra transistors are connected by their emitters to bases of appropriate main transistors. Besides, said extra transistors are connected by their bases and collectors via base feed resistors and collector resistors with power supply.
EFFECT: pulse relative duration, pulse-repetition rate or pulse duration controlled by external signals.
