Web23 de mai. de 2012 · DC offset, if any, is usually very low. Removing this offset only allows a 0.01 dB gain or so. But it introduces a phase shift in the remaining part of the signal leading the limiter to work harder. Even phase linear filters introduce a greater ripple in the magnitude than the 0.01 dB gain which can be expected.
