  • Peak detector
    Patent number: 4112381
    Abstract: A peak detector employing an integrator, a D.C. tracking circuit and a zero-crossing detection circuit produces a logic signal indicating the occurrence of a peak of an input voltage signal. Hysteresis in the zero-crossing detection circuit and integration of the input voltage signal improves the noise rejection of the peak detector.
