SHORTWAVE RADIO RECEIVER COMPRISING A MEANS FOR DETECTING A RECEIVED ELECTRIC FIELD FORCE LEVEL AND COMPARING IT WITH A REFERENCE LEVEL, WITH A MEDIUM CHANNEL SELECTOR

摘要

P THE INVENTION CONCERNS A RECEIVER COMPRISING A MEANS FOR DETECTING A RECEIVED ELECTRIC FIELD FORCE LEVEL AND COMPARING IT WITH A REFERENCE LEVEL, WITH A MEDIUM CHANNEL SELECTOR FOR SWITCHING A RECEPTION FREQUENCY ACCORDING TO THE RESULT OF THE COMPARISON. According to the invention, the receiver comprises a circuit 21, the tuning frequency of which is variable and which is connected to a receiver input stage of the receiver. AND A CONTROL MEANS 12 FOR CONTROLLING THE CIRCUIT GIVEN IN ORDER TO OBTAIN A FREQUENCY OF ACCORD ACCORDING TO A FREQUENCY CHOSEN BY THE CHANNEL SELECTOR MEANS. / P P THE INVENTION APPLIES IN PARTICULAR TO RADIO RECEIVERS FOR MOTOR VEHICLES. / P
