WebConducted noise is already in the circuit board by the time the signal arrives at the input of the ADC. The most effective way to remove this noise is by using a low-pass (anti-aliasing) filter prior to the ADC. Including by-pass capacitors and using a ground plane will also eliminate this type of noise. A third source of noise is radiated noise.
