In [[telecommunications]], the term '''carrier shift''' has the following meanings: 

#In the [[transmission (telecommunications)|transmission]] of [[Binary code|binary]] or [[teletypewriter]] signals, [[keying (telecommunications)|keying]] in which the frequency of the [[carrier signal]] is shifted in one direction for marking signals and in the opposite direction for spacing signals.
#In [[amplitude modulation]], a condition that results from imperfect modulation in which the positive and negative excursions of the modulating [[envelope]] are unequal in amplitude.

''Note 1:''  The carrier shift results in a change in [[carrier power]]. 

''Note 2:''  The carrier shift may be a shift to a higher or to a lower frequency.
