CA 2436582

The present invention provides a novel feed forward amplifier ("FFA") and a pilot tone generator-receiver therefor. In an embodiment of the invention, the feed forward amplifier only requires a single oscillator to operate both the pilot tone generator and pilot tone receiver used in conjunction with the amplifier circuitry of the FFA. In another embodiment of the invention, a method is provided of generating and detecting a pilot tone from a single oscillating signal.

La présente invention concerne un nouvel amplificateur à correction aval (FFA) et son générateur-récepteur de signal d'identification. Dans un mode de réalisation de l'invention, l'amplificateur à correction aval nécessite seulement un unique oscillateur pour actionner à la fois le générateur de signal d'identification et le récepteur de signal d'identification, utilisé conjointement au circuit d'amplificateur du FFA. Dans un autre mode de réalisation de l'invention, un procédé permet de générer et de détecter un signal d'identification à partir d'un signal oscillatoire unique.
