Editing Power margin

{{Short description|Power difference}}

In [[telecommunications]], the '''power margin''' is the difference between available [[signal]] [[Power (physics)|power]] and the minimum signal power needed to overcome [[system]] losses and still satisfy the minimum input requirements of the receiver for a given performance level. 

System power [[wikt:margin|margin]] reflects the excess [[signal level]], present at the input of the receiver, that is available to compensate for (a) the effects of [[electronic component|component]] aging in the transmitter, receiver, or physical [[transmission medium]], and (b) a deterioration in [[Wave propagation|propagation]] conditions. ''Synonym'' '''system power margin.'''
