3 Definitions, symbols and abbreviations 3.1 Definitions For the purposes of the present document, the following terms and definitions apply: broadcasting service: radio communication service in which the transmissions are intended for direct reception by the general public NOTE: This service may include sound transmissions, television transmissions or other types of transmission. carrier power: average power supplied to the antenna transmission line by a transmitter during one cycle taken under the condition of no modulation class of emission: set of characteristics of an emission, designated by standard symbols, e.g. type of modulation of the main carrier, modulating signal, type of information to be transmitted, and also, if appropriate, any additional signal characteristics composite: See 'Multiplex (MPX) signal'. difference signal: signal theoretically equal to half the difference between the left and right stereophonic signals, and in practice proportional to this difference enclosure port: physical boundary of the apparatus through which electromagnetic fields may radiate or impinge NOTE: In the case of integral antenna equipment, this port is inseparable from the antenna port. mean power: average power supplied to the antenna transmission line by a transmitter during an interval of time sufficiently long compared with the lowest frequency encountered in the modulation envelope taken under normal operating conditions MultiPleX (MPX) signal: contains all information, including the pilot tone and any supplementary signal which is used to frequency modulate the VHF FM transmitter necessary bandwidth: for a given class of emission, the width of the frequency band which is sufficient to ensure the transmission of information at the rate and with the quality required under specified conditions out-of-band emissions: emission on a frequency or frequencies immediately outside the necessary bandwidth which results from the modulation process, but excluding spurious emissions pilot tone: 19 kHz tone used to recover the stereo subcarrier in the stereo-receiver Radio Data System (RDS): signal containing information on programmes and broadcasting network as defined in EN 50067 NOTE: This signal is carried by a subcarrier at 57 kHz, amplitude modulated by the encoded data with suppressed carrier in a frequency band of ± 2,4 kHz. reference bandwidth: bandwidth in which the emission level is specified spurious emissions: emission on a frequency or frequencies which are outside the necessary bandwidth and the level of which may be reduced without affecting the corresponding transmission of information NOTE: Spurious emissions include harmonic emissions, parasitic emissions, intermodulation products and frequency conversion products but exclude out of band emissions. stereo subcarrier: 38 kHz subcarrier used to carry the difference signal sum signal: signal theoretically equal to half of the sum of the left and right stereophonic signals, and in practice proportional to this sum unwanted emissions: consist of spurious emissions and out of band emissions SIST EN 302 018-1 V1.1.1:2003
