Abstract: 1445767 Pulse modifying circuits SONY CORP 13 Dec 1973 [21 Dec 1972 19 Jan 1973 12 April 1973 4 May 1973] 57789/73 Heading H3T A pulse edge delay circuit comprises an emitter-coupled transistor pair 9, 10 having the base of 10 connected to a bias source and the base of 9 connected to a CR timing circuit 6, 7 and to an input pulse operated clamp for resetting the capacitor charge and for holding 10 off, input pulses also serving to hold transistor 9 off. As shown a positive input pulse at 5 holds transistors 9 and 10 off, a positive pulse edge thus being produced at the collector of 9 since, in this embodiment, the transistor was previously conducting. At the end of the pulse, 10 becomes conducting to produce the leading edge of a pulse at its collector. Capacitor charges and when its voltage exceeds the bias on 9 the conductivity condition of the transistors changes over, producing the trailing edges of the pulses at respective collectors. Retriggering of the circuit during the timing cycle may be prevented by using the output of collector 10, via 26 and 31, to hold the clamping transistors 1 and 30 off. The circuit will then act as a frequency divider. In addition a diode 32 prevents the capacitor charging between input pulses sufficiently to saturate transistor 9. Capacitor 9 could be connected in parallel with resistor 6 and the Schmitt trigger type bias at the base of 10 could be replaced by a fixed bias (Figs. 1 and 3, not shown). Alternative methods of holding transistor 10 off during the input pulse are, raising the common emitter potential during the pulse (Figs. 4 and 5, not shown) and cutting off a constant-current transistor replacing resistor 21 (Figs. 1 and 3, not shown). In Figs. 10 and 12, not shown, the output from 10 is used to reset the capacitor charge to the starting level at the end of the output pulse.
