DEVICE FOR DELAY OF PULSES AND FREQUENCY DOUBLING Russian patent published in 1994 - IPC

FIELD: pulse equipment. SUBSTANCE: device for delay of pulses and frequency doubling has first and second OR-ELSE gates. First input of second gate is connected to input wire and input of inverter, second input of second OR-ELSE gate is coupled to output of first gate and output wire of pulses of doubled frequency, output of inverter is linked to cathode of first diode which anode is connected to first input of first OR-ELSE gate. Cathode of second diode is connected to input wire, its anode is coupled to second input of first OR-ELSE gate. Time-setting capacitor is placed between inputs of first OR-ELSE gate. Device is inserted with first and second transistors which emitters are connected correspondingly to cathodes of first and second diodes, which collectors are linked to anodes of diode and which bases are interconnected and are linked to common wire through regulating element. EFFECT: increased precision of setting of values of durations delays and pulses with simultaneous expansion of range of their control. 2 dwg
