Abstract
Montages permettant de coupler en croix des compresseurs et des expanseurs bilinéaires connectés en série. Ces montage comportent le couplage de composantes de signal présentes sur une voie de signaux dans un premier circuit avec une voie de signaux dans un premier circuit avec une voie de signaux d'un autre circuit et un couplage en croix assuré par l'utilisation d'un circuit de commande commune pour les dispositifs connectés en série. Application à la réalisation de compresseurs-expanseurs pour audio-appareils.Mounts allowing cross coupling of compressors and bilinear expanders connected in series. These arrangements comprise the coupling of signal components present on a signal channel in a first circuit with a signal channel in a first circuit with a signal channel of another circuit and a cross coupling ensured by the use of a common control circuit for devices connected in series. Application to the production of compressor-expanders for audio-devices.
