Abstract

SKLOP KOLA ZA PROMENU OPSEGA KOD TJUNERA. Za pojačanje viskoke frekvencije sadrže tjuneri generalno predstepene (1, 1', 1") sa MOS-tetrodama (4) za svaki od podopsega tjunera. Prema pronalasku se promena opsega ostvaruje tako da "source" priključak (S) predstepena kojeg treba aktivirati (1) može preko jednog otpornika (10) preko prekidačkog uredjaja (9) da se priključi na referentni potencijal.
