ABSTRACT:
A magnetically recorded representation of an electrical binary waveform is transduced to an electrical signal wherein the binary waveform transitions are represented by peaks in the electrical signal. A delayed replica of the transduced signal is formed, and at least one of the transduced signal and replica signal is dynamically biased. These two signals are then compared to detect relative polarity reversals therebetween and to generate a binary waveform whose transitions correspond to said reversals and is therefore a replica of the magnetically recorded binary waveform.
