Line 1:

'''Signal transition''': In the [[modulation]] of a [[carrier wave|carrier]], a change from one [[significant condition]] to another.

Examples of [[Signalling (telecommunication)|signal]] transitions are a change from one electricalelectric current, voltage, or [[Power (physics)|power]] level to another; a change from one optical power level to another; a [[Phase (waves)|phase shift]]; or a change from one [[frequency]] or [[wavelength]] to another.

Signal transitions are used to create signals that represent [[information]], such as "0" and "1" or "[[mark frequency|mark]]" and "[[space frequency|space]]".
