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

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

sensitivity: minimum wanted signal level required to provide a given level of audio quality

The generated DRM signals (wanted and unwanted) and the blocking signal shall be in accordance in table 1.
