ABSTRACT:
Digital broadcasting of a sound program takes place in a channel of a set of channels. In each channel other than that dedicated to digital broadcasting, the television channel has a spectrum of spectral lines separated by low spectral power density intervals. Digital broadcast is achieved by digital modulation (for instance OFDM) of the transmission with frequency multiplexing using a spectrum interlaced with that of the television. The digital signal is recovered by comb filtering on reception.
