Abstract

A group of binary triggers is interconnected to form a counter. The first stage of the counter has its trigger input connected to receive pulses from an oscillator. The counter state represents the number of pulses that the oscillator has produced. Circuits of this general type perform, for example, timing operations. The oscillator is turned on and off by a gating circuit. This receives inputs from circuits that establish the length of the count.

Delay Counter Reset

A group of binary triggers is interconnected to form a counter. The first stage of the counter has its trigger input connected to receive pulses from an oscillator. The counter state represents the number of pulses that the oscillator has produced. Circuits of this general type perform, for example, timing operations. The oscillator is turned on and off by a gating circuit.

This receives inputs from circuits that establish the length of the count.

The binary triggers are of the type that are AC coupled. This coupling is a capacitor connecting the first binary trigger stage to receive the oscillator output and each other trigger stage to receive the output of the preceding stage. The binary triggers also have DC inputs for resetting the triggers to a state representing the beginning of a count.

The triggers have their reset inputs connected to receive the signal that is applied to the oscillator from the gate circuit. Thus, when the oscillator is turned off, the counter is reset. The reset voltage is maintained at the trigger inputs until the oscillator is next turned on.
