Boie Werner: Broadcast receiver adapted for analog and digital signals. Thomson Multimedia, February 14, 1996: EP0696854-A1 (119 worldwide citation)

Background: Digital satellite TV broadcasting systems use an analog IF input followed by an analog QPSK-demodulator and analog lowpass filters prior to A/D conversion. Normally, two A/D converters would be required for digital demodulation of the in phase and of the quadrature component. Gist of the ...
