ABSTRACT:
The invention provides a pulse generating circuit including a single timer or counter which conducts both a event base count and a subsequent time base count according to clock signals about the event and time base counts, any one of which is selected by a selector. A pulse signal is generated from a RS flip-flop circuit. When the time base count follows the event base count, during the event base count, the output signal from the flip-flop is a 0 signal. During the time base count, the output signal from the flip-flop is a 1 signal. The event base count defines a delay of a pulse generated from RS flip-flop circuit and the time base count defines a width of the pulse.
