FIELD: technology for simultaneous broadcasting radio-transmission of signals with analog modulation and of digital transmission signals.
SUBSTANCE: in accordance to the invention, amplitude-modulated signal of simultaneous broadcasting radio-transmission, which incorporates digital transmission signal and analog transmission signal in one transmission channel, is characterized by the fact that one side band of carrier of signal of simultaneous broadcasting transmission is modulated by digital transmission signal, and another band is modulated by correcting signal, which ensures provision of analog transmission signal of waveform envelope for demodulation. Generator of amplitude-modulated signal is intended to be used for generation and transmission of aforementioned signals.
EFFECT: creation of method for simultaneous transmission of digital and analog signals through a single channel.
