| 摘要 |
A data carrier (1), or a circuit (2) for such a data carrier (1), which is arranged to receive a carrier signal (CSM) amplitude modulated in conformity with data (DA), is provided with data regenerating means (12) for regenerating data (DA) modulated on the amplitude modulated carrier signal (CSM), and with data processing means (28) for processing data (DA), the data regenerating means (12) additionally including receiving storage means (20) for temporarily storing a predetermined quantity of data (DA), and also detection means (22) for detecting the fact that the predetermined quantity of data (DA) has been buffered in the receiving storage means (20), the detection means (22) being capable of generating control information (CI1) whereby the data processing means (28) can be switched over from a power saving operating mode to a normal operating mode.
