The reason is simply that, in analogue and a.c. circuits, signals are based on repetitive waves (often sinusoidal in shape). We can refer to a point on such a wave in one of two basic ways: either in terms of the time from the start of the cycle or in terms of the angle - a cycle starts at 0° and finishes at 360°. In practice, it is often more convenient to use angles rather than time, however the two methods of measurement are interchangeable. (:nl:)(:table style="clear:both":)
