The ability of the eQADC to sample an analog waveform in the time domain, perform Finite Impulse Response (FIR) or Infinite Impulse Response (IIR) filtering also in the time domain, but to down sample the results in the angle domain. Resulting in a time domain filtered result at a given engine angle.
