[DE] Die Erfindung betrifft ein Mobilfunkgerät mit einer Freisprecheinrichtung (6), die Kombinationsmittel (30) zur Kombination von mindestens zwei akustischen Eingangssignalen (9) und ein adaptives Filter (14) zur Filterung des kombinierten Ausgangssignals (23) der Kombinationsmittel (30) aufweist. Zur Erzielung einer verbesserten Sprachqualität wird vorgeschlagen, dass ein Hochpassfilter (11) zur Filterung der akustischen Eingangssignale (9) vorgesehen ist.
[EN] A mobile radiotelephone set has a handsfree device (6) with combination means (30) for combining at least two acoustic input signals (9) and an adaptive filter (14) for filtering the combined output signal (23) of the combination means (30). In order to achieve a better voice transmission quality, a high-pass filter (11) is provided for filtering the acoustic input signals (9).
[FR] Un appareil radiotéléphonique mobile comprend un dispositif mains libres (6) avec un élément combinatoire (30) pour combiner au moins deux signaux d'entrée acoustiques (9) et un filtre adaptatif (14) pour filtrer le signal combiné de sortie (23) de l'élément combinatoire (30). Afin d'obtenir une meilleure qualité de transmission de la voix, un filtre passe-haut (11) filtre les signaux acoustiques d'entrée (9). |
