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:
adjacent channel selectivity: measure of the capability of the receiver to receive a wanted modulated signal without
exceeding a given degradation due to the presence of an unwanted signal which differs in frequency from the wanted
signal by an amount equal to the adjacent channel separation
blocking: measure of the capability of the receiver to receive a wanted modulated signal without exceeding a given
degradation due to the presence of an unwanted input signal which differs in frequency from the wanted signal by a
specified amount
integral antenna: antenna which is detachable from the equipment without the use of any tools, and not using a 50 Ω
or 75 Ω external connector
NOTE: A device that uses a supplied earphone as the antenna has an integral antenna.
sensitivity: minimum wanted signal level required to provide a given level of audio quality
3.2 Symbols
For the purposes of the present document, the following symbols apply:
dBFS: decibels relative to Full Scale in accordance with AES17 [i.5]
dBm: decibels relative to 1 mW of power
dBµV/m: decibels relative to 1 µV/m
