Abstract
Detected weak signals representative of digital data signals are amplified which produces distorted digital data signals comprising an alternating current (A.C.) voltage signal component and a direct current (D.C.) voltage signal component. A processing circuit filters out the D.C. voltage signal component and converts the A.C. signal component into two substantially D.C. voltage signals representative of the peaks of the A.C. voltage signal component. These substantially D.C. voltage signals are applied across a voltage divider to provide voltage signals representative of the peak voltages of the original detected weak signals and to provide intermediate voltages which are uneffected by changes in magnitude and distortion of the A.C. voltage signal component of the digital data signals.
