ABSTRACT:
Receiver comprising a cascade of first to N resonance amplifiers (SA1, SA2, SA3), an output thereof being coupled to signal processing means (TO, SD, PK, LP1, S) for deriving a baseband modulation signal. To improve the signal to noise ratio said cascade is included in an RF input stage of the receiver for a distributed selective amplification of an RF reception signal, preferably with an impedance level of the individual resonance amplifiers within said cascade of first to N resonance amplifiers increasing in signal downstream direction.
