Abstract

UREDJAJ ZA PRETVARANJE ELEKTRIČNOG SIGNALA U PROPORCIONALNU FREKVENCIJU, sa najmanje jednim prebacivačem polariteta (1), jednim integratorom (3;C) koji je uključen iza njega i koji sadrži kondenzator (C), komparatorom (6) koji je uključen posle integratora (3;C) radi praćenja integrisanog signala (uC), jednim flip-flopom (7) koji je uključen posle komparatora (6), jednim prebacivačem (9) upravljanim pomoću flip-flopa (7) a koji služi za priključivanje i isključivanje referentne struje (IR), jednim izvorom (10) konstantne struje koji daje referentnu struju (IR), upravljačkim kolom (13; 14 odn. 11;12) za stvaranje periodičnog signala prebacivanja (A odn. B) za prebacivač polariteta (1), i jednim izvorom signala (16, 61; 62; 63; 64; 15), naz načen time, daje izvor (16, 61; 62; 63; 64; 15) signala postavljen u ulaznom delu integratora (3;C), da je izmedju naponsko/strujnog pretvarača (3) sadržanog u integratoru (3;C) i kondenzatora (C) smešten drugi prebacivač (5) polariteta koji se upravlja istim signalom prebacivanja (A, B) kao i prvi prebacivač polariteta (1), i da je na izlazu uredjaja postavljen izlazni delitelj frekvencije (8). Prijava sadrži još 12 zavisnih zahteva.
