Abstract

Un récepteur radio reçoit différents signaux émis par deux syntoniseurs de façon simultanée. Les deux syntoniseurs peuvent être un syntoniseur pour le son et un syntoniseur pour les informations de trafic. Chaque syntoniseur comporte un oscillateur local. Lorsque la fréquence de réception d'un syntoniseur interfère avec la fréquence de réception de l'autre syntoniseur, la fréquence de réception de l'un quelconque des syntoniseurs est modifiée à une fréquence ne provoquant pas d'interférence. Par conséquent, les deux syntoniseurs peuvent recevoir des signaux de qualité élevée.
