AUTOMATIC THRESHOLD TRACKING SYSTEM ABSTRACT OF THE DISCLOSURE A magnetic recorder including a playback circuit for decoding a ternary waveform digital data signal is dis- closed, wherein positive and negative threshold levels, used to distinguish between signal levels representative of data ones from signal levels representative of data zeros, are automatically adjusted to compensate for occasional reductions in overall signal level that can occur due to dropouts and modulation noise on the magnetic medium. Two sample and hold units are used to generate an output signal whose amplitude reflects only those signal levels that are greater than some minimum absolute value. This output signal is filtered and then used to generate the compensated positive and negative threshold levels.
