Transmitting and receiving device

A transmitting and receiving device comprising:

• a transmitting device for producing a transmission signal;
• a receiving device for producing a received signal;
• and
• a compensation device which is connected to the transmitting device and to the receiving device and which at least reduces any crosstalk which is produced by the transmitting device in the receiving device, comprising:
• a signal conditioning unit for forming a compensation signal which maps the crosstalk which is produced by the transmitting device in the receiving device;
• a subtraction device which is connected to the receiving device and to the signal conditioning unit, and which subtracts the compensation signal from the received signal produced by the receiving device, thereby forming a modified received signal with reduced crosstalk;
• at least one control connection via which the formation of the compensation signal can be controlled;
• and
• a monitoring unit having an input side connected to receive at least one of the received signal with reduced crosstalk from the subtraction device or a signal which is proportional to the received signal, and having an output side for driving the signal conditioning unit such that the conditioning unit achieves maximum compensation for the crosstalk.
