Jos jednom malo detaljniji frekvetni odziv od 0Hz do 30MHz modula sa AD9850

[Image: attachment.php?aid=9397]

PS: Kako je korisno kad se ima veliki BW na DSO osciloskopu, pustis sweep signal iz generatora, na osc usporis vremensku bazu i sa jednim od onih 15 raspolozivih trigera smiris sliku i dobije se prelep vobler, ne treba ni Y ulaz Wink

Ahh, pa ova klivuljica bi mogal i da se programski ispravi, naravno sa jednim VCA ili PGA!
Evo imam zavistnost, pa kada generisem signal na toj-i-toj ucestanosti posalji gain toliki-i-toliki i eto flat response! To bese feed-forward ? Wink
