WebAug 25, 2024 · Since 3-dB attenuation is only a modest amount (half-power), many applications need to define bandwidth at higher attenuation levels, such as 60 dB. This leads to a parameter called “roll-off” rate, characterized by how many dB per octave of frequency or dB per decade the attenuation increases. Q: How is the roll-off rate characterized?

WebHow to convert power in dBm to dBW.
