Osh!...we're living on planet earth of million years old, while the oldest civilization found about 4000 years ago (absolutely young compared to the age of this universe). so, while we're not YET exist in this world, many things happened, right? Then, when we are NO LONGER exist million years ahead, do you think there will be a new entity living on this earth? And, bonus question: do you think there are similar worlds as our 'known world' out there; spread unevenly beneath galaxies? Thanks for answering these silly questions...

I'm working on a yig notch filter that uses TTL "active strobes" as latching functions. I understand TTL logic, but I don't know exactly what strobe signals are, so I don't know if the signals I'm looking at are correct or not.
