I just failed with some of my facts in my brain haha. Kinda getting things mixed up.
I knew phase cancelation never works 100% (Cadillac did it in their radios by recording tire noise for a while and it worked kinda...). I guess I was kind of wondering about the "perfect case" I guess.
Unlatching the carrier makes total sense and is the simplest answer, haha. The Frostwave one gets around that by including a blend to go between internal and external carriers. Totally makes sense. Should give it another shot! I guess I was hoping for the octave up and DC in my head (when just working through the problem in theoretical situations). Got some routing problems/thoughts to work out!
ARP just listed the CMOS switching as digital in their service manual haha. (The only reason I said that). Makes sense either way (and parallels the BBD/CCD argument with clock signals and the like).
Thanks for the help!
