Title (EN) RADIO-RECEIVER AND/OR RADIO-TRANSMITTER STATION
(FR) INSTALLATION RADIO-RECEPTRICE ET/OU RADIO-EMETTRICE
Abstract: front page image
(EN)The radio-receiver and/or radio-transmitter station may be tuned on a given frequency within spectro or radio frequency range. The receiver and/or transmitter comprise a manually actuable device, such as a control panel or an adjusting button, to select the given frequency. The receiver comprises also an intermediary frequency stage, comprising a plurality of intermediary frequency filters, having each a different range width, and a demodulating stage working according a plurality of demodulation modes, while the transmitter comprises a modulation stage working according a plurality of modulation modes. In the rangement, they are provided control means which control the device for the selection of the given frequency and which provide for the automatic selection of an intermediary frequency filter and one of the demodulation modes in the receiver, as well as one of the modulation modes in the transmitter.
(FR)L"installation radio-receptrice et/ou radio-emettrice peut etre syntonisee sur une frequence donnee a l"interieur d"une bande de frequences radio ou spectre. Le recepteur et/ou l"emetteur comprennent un dispositif actionnable manuellement, tel qu"un tableau de commande ou un bouton de reglage, pour selectionner la frequence donnee. Le recepteur comprend egalement un etage de frequence intermediaire, comportant une pluralite de filtres de frequence intermediaire ayant chacun une largeur de bande differente, et un etage de demodulation pouvant fonctionner selon une pluralite de modes de demodulation, tandis que l"emetteur comprend un etage de modulation pouvant fonctionner selon une pluralite de modes de modulation. Dans l"installation sont prevus des moyens de commande qui agissent sur le dispositif pour la selection de la frequence donnee et qui servent a selectionner automatiquement un filtre de frequence intermediaire et un des modes de demodulation dans le recepteur, ainsi qu"un des modes de modulation dans l"emetteur.
