View source for Dropout (communications)

{{Short description|Momentary loss of signal}}
A '''dropout''' is a momentary loss of [[signalling (telecommunication)|signal]] in a [[communications system]], usually caused by [[noise]], [[radio propagation|propagation]] anomalies, or system malfunctions.  For [[analog signal]]s, a dropout is frequently gradual and partial, depending on the [[cause]].  For [[Digital signal (broadcasting)|digital signal]]s, dropouts are more pronounced, usually being sudden and complete, due to the [[cliff effect]].  In [[mobile telephony]], a dropout of more than a few [[second]]s will result in a [[dropped call]].
