摘要： Crosstalk is eliminated in a transceiver which is operated in a frequency-division-multiplex full duplex mode. The technique is suitable in particular for what is referred to as software-defined telecommunications equipment. The frequency division multiplex transceiver has a baseband block, a transmit path and a receive path which respectively transmit and receive on different frequencies (full duplex mode). Furthermore, an auxiliary transmit path is provided which is connected to the receive path and which adds to the received signal a signal whose phase is shifted by 180° with respect to the phase of the crosstalk portion in the first receive path at the summation or superimposition point and which has the same frequency range as the transmit signal. The auxiliary transmit path is driven here, independently of the first transmit path, by the baseband block so as to minimize the crosstalk sensed by the baseband block.

摘要： A tool holder for holding a tool has at least one sensor for measuring an operating parameter of the tool holder or the tool during the operation thereof and generating measured value signals which are fed to a signal processing unit for evaluation. The sensor is a surface acoustic wave sensor operating according to acoustic wave principles and its measured value signals are readable in a contactless manner by means of radio waves. The surface acoustic wave sensor requires no current supply circuit but instead draws transmission energy required for transmission of the measured value signals to the signal processing unit from a high frequency interrogation signal, that is transmitted by radio waves from the signal processing unit and is received by the surface acoustic wave sensor.
