Four immediately come to mind. 2/ What is the mechanism in an oscillator, that is responsible for phase noise? [In only one sentence please] If this is known, then it becomes easier to design low phase noise oscillators. I hope you enjoy these questions,.................................Don. _______________________________________________ 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. _______________________________________________ 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.
