Merni lanac za DIY audio

(03-01-2021, 08:02 PM)gorso69 Wrote: ali izlaz je katastrofa

Proverio sam pločicu i komponente,sve deluje ok.Na kraju pota do R2 signal je još uvek u redu ali onda kreću izobličenja.
Za danas mi je dosta sutra je novi dan možda bude bolji od ovog.

Ovo sto ti nazivas katastrofom je daleko bolje od rezultata u sledecem primeru koji si postavio gde imas jasno definisanu sinusoidu osnovne frekvencije samo malo fazno pomerenu (filtar "zavrce" fazu).
Ne znam sta ocekujes na izlazu filtra? Koristis GF MA3733 koji je radjen sa ICL8038 i ima izoblicenja sinusa veca od 1%, ako je dobro podesen ( u sta sumnjam) .
Jasno se vidi da ti je dominantna osnovna frekvencija, samo sto je u drugom primeru to drasticno.
Imas dva problem, koristis veoma los generator i drugi problem koji je malo veci, je precizno podesavanje filtra. Notch ti nije dobro podesen ni u jednom slucaju s'tim sto je u drugom losije.
Na izlazu iz notcha trba da dobijes neke "hijeroglife", zavisno od primese harmonika u rezidumu, samo se treba truditi da budu sto manji po amplitudi prilikom podesavanja filtra.
Braca ti je lepo sugerisao da potenciometar za podesavanje "razbijes" na sto mnaji opseg da bi jasno osetio kad si prosao kroz vrh notcha.
Ako uzmes premali opseg podesavanja moze se desiti da su usao u temperaturnu (ili neku drugu) nestabilnost frekvencije generatora i opet nista od preciznosti. 
Znaci, taj GF mozes da zaboravis kad je u pitanju fino stelovanje notcha.

Novac je sredstvo a ne cilj.
