Abstract

77, prvi komparator 78 za uzorkovanje integriranog signala prvom frekven-cijom uzorkovanja i za generiranje prvih signala za jedno stanje podataka kada je integrirani signal pozitivan i za drugo stanje podataka kada je integrirani signal negativan, i digitalno analogni pretvornik 80 za obradu binarne riječi i signala bita predznaka i pretvorbu binarnih riječi u kvantizirane signale q(t), pri čemu su ti signali pozitivni ili negativni u ovisnosti o stanju spomenutog bita predznaka, naznačen time da su ulazi drugog komparatora (91) spojeni na ulaz analognog signala (VIN) i na izlaz digitalno analognog pretvornika (80), dok mu je izlaz spojen na ulaz sklopa za uzorkovanje rezultata usporedbe (92), čiji ulaz za takt je spojen na izvor prve frekvencije uzorkovanja (CLK AT Fs), dok mu je izlaz za signale spojen na prvi ulaz logičkog sklopa (93) na čiji drugi ulaz je spojen izlaz iz spomenutog prvog komparatora i sklopa za uzorkovanje (78) putem bistabila (FLIP FLOP), pri čemu je na par upravljačkih ulaza logičkog sklopa (93) spojen par izlaza (MSB, LSB) posmačnog spremnika (98), a njegovi izlazi spojeni su redom na ulaz za bit predznaka digitalnog analognog pretvornika (80) i filtera (101), na ulaz za posmak ulijevo i udesno te na ulaz za rad bez posmaka spomenutog posmačnog spremnika (98), čiji ulaz za takt je spojen na izvor prve frekvencije uzorkovanja (CLK AT Fs), dok su mu izlazi za podatke spojeni na ulaze digitalno analognog pretvornika (80) i na ulaze digitalnog filtera (101) čiji izlaz je spojen na izlaz sklopa (OUT). Prijava sadrži još 4 patetna zahteva.
