Abstract
When communicating using active load modulation in a Radio Frequency Identification (RFID) system, a carrier signal having a carrier frequency is received from a reader device. In response, a modulated signal is generated and a burst of a sending signal is transmitted. The sending signal is decayed at the end of the burst.
