Hallo an alle,
ich muss derzeit einen analogen Bandpass 3.Ordnung von 300-3400Hz
entwerfen, und soll diesen vor der eigentlichen Fertigung mit LT-Spice
durch simulieren. Allerdings startet die Simulation nicht. Im Logfile
wird folgendes abgespeichert:
Circuit: * D:\Hochschule\Dropbox\KE\Bandpass LTSpice\Bandpass.asc
Early termination of direct N-R iteration.
Direct Newton iteration failed to find .op point. (Use ".option
noopiter" to skip.)

Hat jmd einen Tipp für mich?
Danke schonmal im vorraus
