Abstract
The present invention relates to a receiver for coded electromagnetic pulses, consisting of: a) a current/voltage supply (150), b) an RF receiver section (350) consisting of 1) an RF input circuit (antenna circuit, 360), 2) an RF/IF amplifier and mixer section, 3) an RF oscillator (340), 4) a demodulator (380), 5) a signal amplitude control circuit and level converter (390> c) a decoder unit (250) with code selection switching (260), d) an interface (input/output circuit, 850), wherein e) the receiver section (350) has an oscillator (340) which oscillates in a wide frequency band and wherein f) the resonant circuit (370) of the antenna (360) has a tuning capacitor and the decoupling of the received signal takes place via a capacitive divider and this divider is connected to earth, in RF terms, via a capacitor, in accordance with Patent Application No. 37 41 324.4. In order to extend the range of the transmitter-receiver system, with a construction which is furthermore simple, it is proposed according to the invention that a low-pass filter (385) for the useful signal from the RF receiver circuit be provided behind the demodulator (380). <IMAGE>
