| process by which a radio transmitter produces radio-frequency energy for the purpose of radiocommunication
Note 1 to entry: In radiocommunication, the term “emission” should not be used in the more general sense of radio-frequency emission. For example, the production of the part of electromagnetic energy from the local oscillator that is transferred to external space, is a radiation and not an emission.
Note 2 to entry: The term “emission” is also used for the radio waves or signals produced (see IEV 161-01-09), for the production of any waves or particles (see IEV 702-02-03), as a synonym for a programme in broadcasting and for transmission in broadcasting, and for a release into the environment (see IEV 904-01-11).
Note 3 to entry: In French, the term “émission” is also used for the concept represented by the English term “sending” of a signal.
