Raw Blame History

Bandbredden hos en signal eller utsändning mäts i hertz (\unit{\hertz}). Man mäter signalens bandbredd som skillnaden mellan utsändningens högsta och lägsta sändfrekvens.

Bandbredden anger alltså hur mycket spektrum signalen tar i anspråk. Vanligtvis mäter vi bandbredden hos en signal mellan de frekvenspunkter där den spektrala effekten har sjunkit till $\frac{1}{2}$ (motsvarande $\qty{-3}{\dB}$) av topvärdet.
