Carrier Signal Related Entries Web Links New/Updated Information Note: Many topics at this site are reduced versions of the text in "The Encyclopedia of Networking and Telecommunications." Search results will not be as extensive as a search of the book's CD-ROM. A carrier signal is a specific frequency in an analog communication channel that is modulated with an information-carrying signal. Carrier signals are commonly used in AM, FM, and other radio transmissions to differentiate among channels. When you turn a radio dial, you are selecting a carrier frequency. The radio then amplifies the signal carried on the selected frequency. In AM (amplitude modulation), modulation changes the strength or amplitude of the carrier signal. In FM (frequency modulation), the frequency of the carrier signal is modulated. Copyright (c) 2001 Tom Sheldon and Big Sur Multimedia.
