Patent ID: 7049884

Claim:
A demodulation arrangement for a radio signal, comprising: an I/Q mixer comprising an input and an intermediate frequency output comprising at least two taps, wherein the mixer is configured to convert an input signal at a first frequency to a real signal component and an imaginary signal component at a second frequency, wherein one of the at least two taps is configured to provide the real signal component and another of the at least two taps is configured to provide the imaginary signal component; a limiting circuit comprising at least two input connections and at least two outputs, wherein one of the at least two input connections is connected to one of the at least two taps of the intermediate frequency output, and is configured to limit an amplitude of signals applied to its inputs, and wherein the amplitude-limited signals are tapped off at the at least two outputs; a demodulator circuit comprising at least two inputs, wherein one input is connected to one of the at least two outputs of the limiting circuit, and comprising an output, wherein the demodulator circuit is configured to convert signals that are applied to the at least two inputs thereof to a demodulated signal, wherein the demodulated signal is tapped off as a sequence of pulses at the output thereof; and a pulse shaper circuit comprising an input coupled to the output of the demodulator circuit, and comprising an output, wherein the pulse shaper circuit is configured to convert pulses of the sequence of pulses having pulse amplitudes that are greater than a first threshold value to output pulses having a predetermined first amplitude.
