Heh, that's a good point, you can't just sit there and trigger the thing 10,000 times per second for 24 hours... > Also the relatively low ADC resolution and nonlinearities > will tend to limit the effective resolution in determining the zero > crossing locations. I stand by my assertion, though, that all you're going to get with high sampling precision is a lot of well-characterized random noise determined almost solely by outside factors. It's an interesting question, but one that can't be answered without knowing more about the symptom that started the whole thread. -- john, KE5FX _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
