"WebMay 2, 2015 · The frequency at which the input signal is attenuated by 3 dB is called analog input bandwidth. If one sends an input sinewave at the AIB frequency, before being digitized it is attenuated by 30% (which is unlikely acceptable). Thus, it’s preferable that maximum input frequency should be about 1/3 – 1/5 of the AIB. " - Small signal –3 db bandwidth
