Abstract
A device for digital demodulation of the video and audio elements of a television signal has a digital preprocessing stage for conditioning a complex digital signal for digital demodulation of a television signal at intermediate frequency, mixing devices for video and audio elements of the complex digital signal shifting the video sub-carrier and the audio sub-carrier, which is offset by the video sub-carrier frequency, to the frequency 0, digital audio-FM demodulators and parallel paths of mixing devices for the demodulation of the audio signals, so that fully digital signal processing of television signals from the intermediate frequency, with limited filter complexity can be performed.
