WebDecimation, or Interpolation, is the averaging method, which combined with oversampling, which increases the resolution. Digital signal processing that oversamples and lowpass-filters a signal is often referred to as interpolation. In this sense, interpolation is used to produce new samples as a result of ‘averaging’ a larger amount of samples.
