摘要： The ON and OFF states of a second device are controlled by a first device through a three-conductor bus. The bus carries data, clock, and enable signals and the second device is in the OFF state when all the signals of the three-conductor bus have an L level. The second device is in the ON state when at least one of the signals has an H level (higher potential than the L level). The enable signal is set to the H level during the data transmission. Otherwise, it carries an L level, while the data or clock signal has an H level. The system obviates an additional housing pin. The operating state information is transmitted relatively rapidly.

摘要： A transmitting device generates a modulation signal depending on data to be transmitted. The transmitting device includes a transmission frequency generation device that is controlled depending on the signal in order to produce a transmission frequency corresponding to the modulation signal. A calibration device is provided for automatically calibrating the amplitude of the modulation signal during the operation of the transmitting device. This eliminates time-consuming and therefore costly adjustment steps during the production of the transmitting device.
