If you filter a square wave, you have a lot more harmonics than if you filter a signal that is already nearly sine. Hence the DAC stage gives you a higher signal purity. And as filters are never optimal, you'd rather go with a more pure signal :-) Attila Kinali -- Why does it take years to find the answers to the questions one should have asked long ago? _______________________________________________ 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.
