Abstract:
An AM simulcast broadcast signal combining a digital transmission signal and an analogue transmission signal in one transmission channel. The digital transmission signal is modulated to one sideband of a carrier of the transmission channel and a correcting signal (C) is modulated to the other sideband of the carrier of the transmission channel, which correcting signal (C) is determined so that the envelope demodulation of the transmission channel represents the analogue transmission signal.
