Gain
Gain describes the ratio of output to input level. In a receiver it can occur before or after digitisation and is often expressed in dB.
Also found under: Gain · Verstärkung · RF Gain
A concrete example
More input gain can make a weak signal more usable while the converter remains below overload.
What to keep in mind
Louder audio or a brighter waterfall does not automatically mean a better signal-to-noise ratio.
