Carrier Frequency

In telecommunications, carrier frequency is the frequency (the number of waves per second) of a carrier wave (a wave that carries a signal to convey information). Carrier frequency is measured in Hertz (Hz). For example, a carrier frequency of 10 Hz means that there are 10 carrier waves per second. Carrier frequency is an important concept in radio and television broadcasting. By adding an input signal to the carrier wave, the wave’s frequency can be modulated, encoding this additional information inside the wave. This technique is known as frequency modulation (FM), which gives its name to FM radio.

What Small and Midsize Businesses Need to Know About Carrier Frequency

Businesses in telecommunications should be familiar with the notion of carrier frequency. By combining inputs with carrier waves, frequency modulation allows senders to lower the costs of data transmission, rather than using very low-frequency waves that require large amounts of power to send.
