The timing of a circuit using a physical delay line is usually much more accurate.

So until now most integrated circuits have used one or the other, according to application requirements.

Up to this time everyone who tried to make an alternating-current motor used a single circuit, just as was in direct current.

The basic circuits used electronic valves, and the heat generated was itself a great problem.

Usually circuits used four wires, two for each phase.

The circuit used the main runway and perimeter track of the airfield.

All the circuits on the same route use a common path for the return current (earth return).

The circuit uses the property of transistors known as "saturation".

Although circuits can use the electrical contacts directly, it is more common to convert them into high and low signals.

Electronic circuits usually use low voltage direct current sources.
