Title: Improvements in or relating to signal generator control circuits
IPC: G06V10/98
Filed: 1960-01-25
Abstract: 938,953. Transistor pulse-generating circuits. BURROUGHS CORPORATION. Jan. 25, 1960 [Jan. 30, 1959], No. 2683/60. Class 40 (6). A pulse generating circuit comprises means for generating an output pulse in response to an input pulse 18 and means for terminating the output pulse upon the application of a further inhibiting pulse 17. In the quiescent state of the circuit transistor 19 conducts so that the right-hand electrode of capacitor 23 is at, substantially earth potential while its left-hand electrode is at - 6 volts, the voltage of supply source 22, as transistor 15 is cut off. The application of pulse 18 switches transistor 15 on; its collector electrode goes sharply positive by 6 volts so that simultaneously the base electrode of transistor 19 goes to +6 volts and transistor 19 is cut-off. The output pulse which is applied to a flip-flop circuit 28 is produced at the collector electrode of transistor 19. Capacitor 23 then commences to discharge through resistor 21; when the base electrode of transistor 19 reaches earth potential the transistor conducts and the output pulse is terminated. Alternatively, if the pulse 18 should terminate before capacitor 23 is discharged, the output pulse will terminate with the trailing edge of pulse 18. In certain circumstances, however, a reject pulse 17 whose leading edge occurs just after that of pulse 18 may be applied to the base of transistor 33 to cause an increase in potential at the base of transistor 35 to switch the latter transistor on. The negative pulse at the collector of transistor 19 is consequently short-circuited; at the same time capacitor 23 is rapidly discharged through transistor 35 and load resistor 26 (of very much smaller value than resistor 21) so that transistor is rapidly brought to a state of conduction once more.
