3 Definition of terms, symbols and abbreviations
3.1 Terms
For the purposes of the present document, the terms given in Directive 2014/53/EU [i.1] and the following apply:
amplitude imbalance: error caused by different amplification of the I and Q signals
antenna port: port of an apparatus which is designed, in normal operation, to be connected to an antenna using coaxial
cable
broadcasting service: radiocommunication 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.
channel bandwidth: frequency band of defined width (as a multiple of the carrier grid) including safety margin for
operation on adjacent channels, located symmetrically around a carrier frequency in the carrier grid
dBc: decibels relative to the 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.
DRM transmitter: device comprising a DRM exciter, RF amplifier and RF system filter
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.
harmonic: component of order greater than 1 of the Fourier series of a periodic quantity
harmonic number: integral number given by the ratio o

broadcasting service: radiocommunication 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.
channel bandwidth: frequency band of defined width (as a multiple of the carrier grid) including safety margin for
operation on adjacent channels, located symmetrically around a carrier frequency in the carrier grid
dBc: decibels relative to the 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.
DRM transmitter: device comprising a DRM exciter, RF amplifier and RF system filter
enclosure port: physical boundary of the apparatus through which electromagnetic fiel
