They both accomplish the same thing but in different ways. The Wenzel design requires gain matching but should be unconditionally stable. _______________________________________________ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
