Carrier frequency
Carrier Frequency
Carrier Frequency (pronunciation: /ˈkærɪər ˈfriːkwənsi/) is a term used in telecommunications and genetics.
Etymology
The term "Carrier Frequency" is derived from the English words "carrier" and "frequency". In telecommunications, it refers to the frequency at which a radio wave is modulated to carry an information-bearing signal. In genetics, it refers to the frequency at which a specific gene variant (allele) is present in a population.
Telecommunications
In telecommunications, a Carrier Frequency is a steady frequency of a signal, such as a radio wave, that is modulated to encode information. This frequency is used as a basis for the transmission of information by variation of some aspect of the carrier signal (its amplitude, frequency, or phase) in response to the information being sent. The term is used in frequency modulation (FM) and amplitude modulation (AM) transmission systems.
Genetics
In genetics, the Carrier Frequency is the frequency at which a specific gene variant (allele) is present in a population. This term is often used in the context of genetic disorders. For example, if a specific gene variant is associated with a disease, the carrier frequency is the proportion of individuals in the population who carry that variant but do not show symptoms of the disease.
