ABSTRACT:
A carrier frequency system is provided with a transmission band of up to approximately 200 MHz with a small number of partial bands of identical magnitude and kind. These partial bands are translated and cut connected through and vice versa in their entirety into a frequency spectrum within the transmission band of a 60 MHz carrier frequency system of quinary group construction. The partial bands which are cut connected through into the other system are suitable for working with the translators of the other system in the same way as with its own partial bands. The filters required for the system are simple and uncomplicated.
