Abstract

Abstract Translated from German Nach dem Verfahren wird wenigstens ein variabler Parameter unabhängig von dem Betrag der Amplitude eines an biologisches Gewebe abgebbaren Impulses (19) eines RLC-Entladestromkreises (5) mit einer Vorrichtung bestimmt. Dazu wird in einer Meßeinrichtung (13), die an den RLC-Entladestromkreis angekoppelt ist und eine Auswerteschaltung (14) aufweist, der zeitliche Abstand zwischen zwei meßbaren Werten (t0 bis t4) des elektrischen Impulses (19) mit einer Zeitmeßschaltung (15) gemessen, dessen elektrisches Ausgangssignal der Auswerteschaltung (14) der Meßeinrichtung (13) zur Bestimmung eines Parameters des RLC-Entladestromkreises (5) zugeführt wird. <IMAGE> According to the method, at least one variable parameter is determined with a device independently of the magnitude of the amplitude of a pulse (19) of an RLC discharge circuit (5) that can be delivered to biological tissue. For this purpose, the time interval between two measurable values (t0 to t4) of the electrical pulse (19) is measured with a time measuring circuit (15) in a measuring device (13), which is coupled to the RLC discharge circuit and has an evaluation circuit (14) The electrical output signal of the evaluation circuit (14) of the measuring device (13) for determining a parameter of the RLC discharge circuit (5) is supplied. <IMAGE>
