A method and a circuit for transmitting or storing a wide-band signal in several, narrow-band channels, wherein frequency modulation and demodulation occur in the wideband channel. The uniformity of the transmission characteristics of the entire system is improved by obviating the necessity for multiple modulators and demodulators in the individual transmission channels.
