Abstract
The disclosed circuit permits AC coupling of digital waveforms and rejects low frequency interference, yet restores proper waveform even to low frequency digital signals which have suffered waveform distortion by having passed through a transmission channel or storage device with limited low frequency response. Said circuit consists of a differentiator bridged across a non-inverting digital amplifier.
