WebThe chopper modulation technique is widespread and essential to mitigate 1/f noise and other low-frequency noise, such as popcorn noise, voltage offsets, and drifts. It is particularly used for sensitive acquisition of relatively weak biopotentials such as EEG, which requires very low input-referred noise, less than 1-2 μV rms.
