Abstract
A signal processor produces a digital signal (Vd), which may be derived from digital information recorded on an information carrier, and applies it to a peak detector for generating a control signal (Vr) which corresponds to the peak value of the digital signal. The digital signal is also applied to a digital amplifier whose gain is controllable by the control signal so that the resulting amplified digital signal (Vv) will drive a digital-to-analog converter to the maximum extent of its conversion range, thereby maximizing the analog output signal (Va) of the converter. The peak detector may be adapted to produce the control signal in accordance with a peak code (Vp) already recorded on the information carrier, which peak code is derived therefrom by the signal processor and indicates the peak digital value of the recorded digital information.
