Title (EN) APPARATUS AND METHOD FOR IF SWITCHING IN A DUAL-TUNER, DUAL-IF HD RADIO AND FM/AM RADIO RECEIVER
(FR) APPAREIL ET PROCEDE DE COMMUTATION DE LA FI DANS UN TUNER STEREO, UNE RADIO STEREO FI HAUTE DEFINITION ET UN RECEPTEUR RADIO AM/FM
Abstract: front page image
(EN)In a dual-channel HD radio receiver (40), when the broadband filter (421) channel is compromised, the broadband channel is inactivated and the narrowband channel is activated. By mixing the signals of the two channels during the change, undesirable audio artifacts can be minimized.
(FR)Dans un récepteur radio stéréo (40) à haute définition lorsque le canal (421) du filtre à large bande est compromis, il est désactivé et le canal à bande étroite est activé. Les artéfacts audio indésirables peuvent être réduits en mélangeant les signaux des deux canaux pendant la modification.
