Schaltung zur Erkennung von Spitzenwerten eines zeitdiskreten Signals durch eine appoximierte Funktion

摘要

A peak detecting circuit capable of accurately detecting a peak of a time discrete signal without increasing a circuit scale. The peak detecting circuit detects a peak of a waveform of a time discrete signal by calculating an approximate function which approximates the waveform of the time discrete signal. A peak of the approximate function is detected according to parameters of the approximate function so that the peak of the approximate function is estimated as the peak of the waveform of the time discrete signal.
