method and device for measuring and analyzing the peak of a vibrant spannungsmessignals

摘要

1. Apparatus for measuring and evaluating the peak values of a pulsatory voltage signal, characterized by means (24, 25, 67, 68 ; 24, 81, 82, 67, 68 ; 24, 91, 92, 94 to 99, 102, 105 to 107, 109), the output signal of which is applied to the input of a measuring and evaluating means (70), and which compares the voltage signal applied with zero potential and for removing the error caused by zero-point drift deducts from the voltage signal those portions of the signal which have a polarity opposed to the polarity of the peak values of the voltage signal as they occur, and which at a predetermined level of the decaying edge of the voltage signal after each peak value has been reached, sets its output signal to zero potential and keeps it at zero potential until the beginning of the reascent of the signal level of the voltage signal at the time of the next pulse.
