Out-of band emissions
The complete sentence:
"For the purpose of this standard the out-of-band domain will be considered as the spectrum within ±5 times the necessary bandwidth either side of the channel centre but excluding the in-band signal."
The context:
Définition d'une émission hors-bande (masque spectral) dans le cadre d'une norme relative à des méthodes de mesure applicables aux émetteurs DRM
My question:
Est-ce que vous pourriez m'aider à comprendre cette phrase ?!! Merci beaucoup.

See explanation below...
Suppose, for the sake of example, that the channel centre frequency is 500 MHz and that the necessary bandwidth is 20 MHz.
In that case, the 'out-of-band domain' they are seeking to define would extend [5 × 20 =] 100 MHz above [= +] and below [= –] the centre frequency, i.e. from 400 MHz up to 600 MHz.

Note from asker:
thank you for your nice explanation Tony, it seems now that everything is clear now ;-) |
