MULTICARRIER TRANSMISSION SYSTEM

摘要

A converter for use in a cable television system and interconnected between a transmission path and a television receiver for selecting any one of a plurality of television signals carried by the transmission path. The converter includes a broadband section for translating all received television signals to intermediate frequencies higher than the frequencies of the received television signals such that no images appear within the band of input signals. A selected one of the television signals at a predetermined higher intermediate frequency is then translated by a narrow band section to a lower frequency of a predetermined television channel for reception by the television receiver.
