PEAK_AND_TROUGH_DETECTOR

Published:2009/7/14 21:35:00 Author:May | From:SeekIC

Uses only two opamps to detect peak and valley voltages of nonsymmetrical waveform. During valley period, D2 conducts and discharges C2 rapidly to lowest value of signal amplitude. C2 charges only slightly through D4 and R2 during positive peaks, thus retaining minimum voltage.-C. Spain, Precision Peak and Trough Detector, Wireless World, 0ct. 1977, p 65.
