Abstract
A signal responding method includes: receiving a carrier signal with a frequency of 125 KHz via an antenna with a resonance frequency of 13.56 MHz; amplifying the carrier signal and performing analog-to-digital conversion on the amplified carrier signal to obtain a digital signal; acquiring, according to the digital signal, a signal characteristic of the carrier signal which comprises at least a frequency and a phase; and encoding response data at the frequency of the carrier signal to obtain an encoded signal, determining an initial phase to output the encoded signal based on the phase of the carrier signal, and outputting the encoded signal via the antenna, such that the encoded signal and the carrier signal are superposed at a same phase.
