Patentansprüche:Patent claims:, i. Radioempfänger, bei welchem neben den auf die Empfangsfrequenz abzustimmenden
Kreisen gegen dieselben verstimmte, künstlich bedämpfte Kreise vorgesehen
sind, dadurch gekennzeichnet, daß die Dämpfung dieser verstimmten Kreise derart gewählt wird, daß durch die verstimmten
Kreise bedingte Spitzen in der Resonanzkurve des Empfängers nicht auftreten. , i. Radio receiver, in which in addition to the to be tuned to the reception frequency
Circles against the same detuned, artificially damped circles provided
are, characterized in that the attenuation of these detuned circles is chosen so that by the detuned
Circular peaks in the resonance curve of the receiver do not occur.2. Einrichtung nach Anspruch 1, dadurch gekennzeichnet, daß die Spulen des
verstimmten Kreises aus Widerstandsdraht passender Dimensionierung gewikkelt
sind.2. Device according to claim 1, characterized in that the coils of the
out of tune circle wound from resistance wire of suitable dimensions
are.3. Einrichtung nach Anspruch 1, dadurch gekennzeichnet, daß die Frequenz
des verstimmten Kreises kleiner als die zu übertragende Frequenz gewählt ist.3. Device according to claim 1, characterized in that the frequency
of the detuned circuit is selected to be smaller than the frequency to be transmitted.
