Drage kolege, dugujem izvinjenje za prethodno postavljene rezultate, a pogotovo za iskaz da THD aktuelnog oscilator nije merljiv.

Razlog za grešku je što sam u mernom lancu imao pogrešan filter - umesto niskošumnog fltera s kondenzatorima od 100nF, tamo je bio jedan stari (prvi koji sam napravio) s kondenzatorima od 10nF i znatno većim otpornicima.

Novi rezultati su u prilogu.
Lepo se vidi niži prag šuma i jasno izraženi harmonici: kod novog oscilatora -113,6/-129,2dBc, kod starog -110/-112dBc.
Naravno, ovo će još biti provereno kada završim modifikaciju filtera (problemi sa trimerom za podešavanje frekvencije).
