ABSTRACT:
A circuit for detecting when peaks occur in an amplitude modulated electrical signal, and for measuring in real time the amplitudes of the detected peaks. The circuit delays the input signal a short time, and then notes when the input signal and its delayed version have the same amplitude, thereby to detect when a peak has occurred. The amplitude of the peak is then measured. This circuit and technique have particular advantages when used as part of a servo control system that positions a read/write head to accurately follow moving tracks of recorded data on magnetic tape, magnetic disks, optical disks, and the like.
