Abstract

PURPOSE: To obtain sure peak detection level signals by constituting a peak detecting circuit by the use of a diode and a capacitor.
CONSTITUTION: An amplifier A1 of input signal, a peak detecting diode D and a capacitor C are provided. Up to the time tp when an output voltage V01 becomes of a peak value, the capacitor C is charged in the direction of the amplifier A1, diode D1, capcitor C. Next, at the time t>tp, the voltages become Vc>V01 and therefore, the input voltage waveform of a comparator A2 become (b) and the output voltage V02 of a comparator A2 becomes like (c), thereby making possible the peak detection.
