Abstract:
Communication device wherein in a first operating modea first converter converts a first signal, which is within a first frequency range, into a second signal, which is within a second frequency range, a band-pass filter unit filters said second signal to a first intermediate signal, a second converter converts said first intermediate signal to a third signal, which is within a third frequency range; alternatively in a second operating mode, for compression of the dynamic range, a fourth signal in said third frequency range is converted initially into a fifth signal in said second frequency range, and then into a sixth signal in said third frequency range,said communication device is characterized in that in said second operating modesaid first converter converts said fourth signal into said fifth signal, said band-pass filter unit uses a limiter circuit to limit said fifth signal in a second intermediate signal and a band-pass filter to filter said second intermediate signal in a third intermediate signal, and a third converter converts said third intermediate signal to said sixth signal.
