    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.

    摘要: A data carrier processing system is provided for receiving an amplitude-modulated carrier signal. The system includes rectifiers and a voltage limiter that limits the d.c. supply voltage that is provided by the rectifiers. The voltage limiter provides a delayed response to amplitude variations in the carrier signal, so as to avoid adverse effects on the modulation of the carrier signal, while also providing an un-delayed response to excess amplitude values, so as to avoid excessive d.c. supply voltage for circuit elements of the data carrier system.
