(FR) MODULATEUR, DÉMODULATEUR ET MODULATEUR-DÉMODULATEUR
Abstract: front page image
(EN)A modulator, a demodulator and a modulator-demodulator are provided. A modulator includes a first intermediate signal processing path adapted to route a first intermediate signal; a second intermediate signal processing path adapted to route a second intermediate signal; a first amplifier coupled into the first intermediate signal processing path; a second amplifier coupled into the second intermediate signal processing path; and a chopper circuit coupled into the first intermediate signal processing path; wherein the chopper circuit is adapted to process the first intermediate signal in dependence on first baseband data; wherein the first amplifier is adapted to amplify the first intermediate signal processed by the chopper circuit in dependence on second baseband data; and wherein the second amplifier is adapted to amplify the second intermediate signal in dependence on the second baseband data.
(FR)L'invention porte sur un modulateur, sur un démodulateur et sur un modulateur-démodulateur. Un modulateur comprend un trajet de traitement de premier signal intermédiaire conçu pour acheminer un premier signal intermédiaire; un trajet de traitement de second signal intermédiaire conçu pour acheminer un second signal intermédiaire; un premier amplificateur couplé dans le trajet de traitement du premier signal intermédiaire; un second amplificateur couplé dans le trajet de traitement du second signal intermédiaire, et un circuit hacheur couplé dans le trajet de traitement du premier signal intermédiaire; le circuit hacheur étant conçu pour traiter le premier signal intermédiaire en fonction de premières données en bande de base; le premier amplificateur étant conçu pour amplifier le premier signal intermédiaire traité par le circuit hacheur en fonction de secondes données en bande de base, et le second amplificateur étant conçu pour amplifier le second signal intermédiaire en fonction des secondes données en bande de base.
