Merenja osciloskopom
#10
Ako bi isli na neke RF modulacije imam ja finih trafocica 1:1 i 1:4 i jezgra FT37-43 (bela) sa kojim bi mogla "junacka" galvanska izolacija da se napravi.

Za "proste" AM / FM modulacije da bi se preneo koji MHz BW-a mora nosioc da bude bar preko 200-300MHz (minimum je x10 ali zbog dinamike/distorzije valja sto vece freq nosioca).
I ja isto naglas razmisljam … Mozda nesto sa NE612 koje isto imam …

Sa AM bi to moglo ovako nesto da izgleda, u "diskretnoj" nekoj varijanti, moze i da se linearizuje preko dodatnog namotaja:

Uglavnom za te RF varijante imam delova ...
