Abstract
A device for processing a modulated real analog television signal has a digital preprocessing stage for conditioning a complex digital signal for digital demodulation of a television signal at intermediate frequency. The digital signal preprocessing is carried out such that subsequent demodulation of the video and audio elements can be carried out at a favorable cost. Therefore a fully-digital signal processing for television signals, from the intermediate frequency, with a limited filter cost is possible.
