SDR RXTX
#11
Nikako da stignem da se ukljucim u temu.

Bojane svak cast! Bas si lepo to sve spakovao.
Sa tim filterima ces se izboriti, negde verovatno postoji greska.

Inace filtere mozes "snimiti" sa nekim signal generatorom (dodatno frekvencmetar ako nema na samom generatoru) i VF sondom.
Uzmes prvo prikljucis VF sondu direktno na generator da bi proverio ponasanje ta dva sklopa. Idealno bi bilo da na opsegu koji meres nema bitnog odstupanja u naponu.
Ako ima odstupanja to moras nekako po tackama da pribelezis da bi kasnije to mogao da kompenzujes u finalnom rezultatu.
Posle uzmes filter i pratis ponasanje. Ako je LPF, od nulte (ili neke najnize) ucestanosti pratis pad napona i kada dobijes na izlazu filtera pola napona od onog koji ulazi, dosao si do -3dB tacke i to ti je Fc (corner-frequency).
Isto tako mozes snimiti i BPF ili HPF.
Naravno, ulazna i izlazna impedanca mora da se ispostuje, dakle to sve meris sa 50Ohm opterecenjem na izlazu filtera (snaga je nebitna).
