O.k., here's the newbie educational question for today.
Analog and TTL modulation. I basically understand the difference (I think) but, don't always understand what the "range" represents and how it affects me as a purchasing decision.
Say for example, you look at an ad for a laser and, they make reference to analog modulation 0-10kHz. Another ad might say analog modulation 0-20kHz. So... what's the difference? (besides "10k" smartass...!you knew you were thinking it!)
Same with TTL, I've seen 20k and 30k in TTL as well.
Why do I want one or the other or, better put, what does 10k versus 20k versus 30k give you?
Thanks! (And yes, I "googled it" first.)
