PURPOSE:To make it possible to detect peak positions from a low frequency to a high frequency by holding the signal level of peak voltage positions and amplifying the difference generated by signal change to detect voltage positions from the change point of the voltage level. CONSTITUTION:An input signal from input terminal 1 is applied to buffer amplifier 2, and a peak voltage detection part consisting of peak voltage hold circuits 3 and 7, difference voltage detector circuits 4 and 8, and differentiating circuits 5 and 9 is connected to the output. In this constitution, peak voltage hold circuits 3 and 7 are reset mutually by signals from differentiating circuits 5 and 9. That is, the difference generated by signal change is amplified while holding the signal level of peak voltage positions, and peak voltage positions are detected as rapid change points of the voltage level. As a result, the peak detection continuous from 0.01 to several 10kHz is possible. |
