Abstract

UREĐAJ ZA PRETVARANJE ELEKTRIČNOG SIGNALA U PROPORCIONALNU FREKVENCIJU. Signal (uH) pomoću prvog prebacivača polariteta (1) periodično menja polaritet, a zatim se pomoću naponsko/strujnog pretvarača (3) pretvara u struju, kojoj se iz jednog izvora signala (15) dobijena referentna struja (IR/2)dodaje-sabira. Taj signal zbira se pomoću drugog prebacivača polariteta (5) periodično menja po polaritetu pomoću drugog prebacivača polariteta (5) sinhrono sa prvim periodičnim prebacivanjem polariteta, da bi se u nastavku integrisao u kondenzatoru (C). Komparator (6) prati napon kondenzatora (uC) u upravlja preko flip flopa (7) jedan prebacivač (9), koji služi za priključivanje i isključivanje referentne struje (IR) koju daje izvor konstantne struje (10). Od frekvencije izlaznog signala (F) D-flip-flopa (7) se u delitelju izlazne frekvencije (8) oduzima referentna frekvencija (fR/2). Uredjaj još sadrži jedan taktni generator (11), šmit-triger (13) kao i dva dalja delitelja frekvencije (12,14). Oni omogućuju periodičnu prebacivanje polariteta korisnog signala sa jednakim poluperiodama po dužini i time potpuno potiskivanje prenosnih greški koje se javljaju zbog nultog (ofset) napona, bez da izlazna frekvencija zbog zaostalog punjenja u kondenzatoru, u trenutku promene polariteta, bude neregularna.
