Abstract

The present invention pertains to an improved voltage- synthesis tuning system with digital memory, in particular for a receiver of television broadcasts, in which a plurality of digital codes, each one respectively identifying a television channel, are stored in a digital tuning memory, at a corresponding plurality of addresses, with an automatic tuning circuit, and with means of modifying the respective digital code, in the presence of frequency drift phenomena in excess of the lock-on field of said automatic tuning circuit; the primary characteristic of the invention consists in the fact that the system finds the television station by modifying the digital tuning code and at the same time verifying the presence of a station identification signal; and the exact tuning is obtained by verifying a signal of elevated slope, coming from the automatic tuning circuit. <IMAGE>
