Automatic detector of maxima and minima of oscillation - uses peak voltage stores for extreme values

摘要

The oscillation is present as an electrical signal. The extreme actual values which have been entered in the peak voltage stores are passed to an evaluation device. The connection is controlled by a clock frequency which is supplied from a frequency generator. The clock frequency controls simultaneously the excitation for the oscillation to be detected, via a multiplier. The detected measured values for the upper and the lower load had to be passed to additional intermediate stores which are not now required. The frequency of the frequency generator is controlled in dependence of the phase position of two electrical signals.
