    摘要: A data carrier receives an amplitude-modulated carrier signal that is amplitude modulated in dependence on data to be received. The modulated carrier signal has a high interval of high amplitude and a pause interval of reduced amplitude. The data carrier has a data processor for processing received data. The data carrier generates d.c. power from the received carrier signal and stores the d.c. power, and detects the pause interval. Upon detecting the pause interval, the data carrier generates an identification signal from the received carrier signal. The identification signal is a logic gating signal. In dependence of the identification signal, a controller causes the application of a clock signal to data processor to be inhibited.
