42、hich is designed, in normal operation, to be connected to an antenna using coaxial cable 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 o

43、r other types of transmission. carrier power: average power supplied to the antenna port by a transmitter during one cycle taken under the condition of no modulation channel L: left hand channel of a stereophonic signal channel R: right hand channel of a stereophonic signal class of emission: set of

44、 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“. dBc: decibels relative to t

45、he unmodulated carrier power of the emission NOTE: In the cases which do not have a carrier, for example in some digital modulation schemes where the carrier is not accessible for measurement, the reference level equivalent to dBc is decibels relative to the mean power P. difference signal: signal (

46、S) theoretically equal to half the difference between the left (L) and right (R) stereophonic signals. S = (L - R) / 2 exclusion band: band of radio frequencies where no measurements are made frequency tolerance: maximum permissible departure of the characteristic frequency of an emission from the a

47、ssigned frequency NOTE: The frequency tolerance is expressed in parts per 106or in Hz. harmonic: component of order greater than 1 of the Fourier series of a periodic quantity harmonic number: integral number given by the ratio of the frequency of a harmonic to the fundamental frequency (second harm

48、onic = 2 fundamental frequency) mean power: average power supplied to the antenna port 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

49、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 ETSI ETSI EN 302 018 V2.1.1 (2
