Hello again,
First off, I want to thank everyone who replied direct and through the group
regarding my recent 10 MHz square to sine wave conversion info request.
I obtained a mini-circuits 10.7 MHz low pass filter from Ebay cheap
enough and I also plan on "rolling my own" based on some of the information
and links provided in your generous replies.
Part 2:
With things in place, I actually looked at the actual square wave output port with
a decent scope to see it's not even close to being symmetrical. The waveform
on-portion (duty cycle) appears (surprising to me) to be much less than 20%
Now I'm under the assumption that proper rounding or conversion of the non
symmetrical 10 MHz square to a sine wave will be a bit more involved.
Before I launch toward part two of this latest saga, I'd really be interested in reading
suggestions and comments regarding methods to improve/fix the 10 MHz waveform
symmetry.
Again, thank you in advance for your replies...
Regards,
