METHOD AND APPARATUS FOR TRANSMITTING A SIGNAL BY A RADIO FREQUENCY IDENTIFICATION READER |
摘要 |
A Radio Frequency Identification (RFID) reader is provided that receives a digital input signal, converts the digital input signal to an analog input signal, and determines whether the digital input signal is an unmodulated signal or is modulated with information. When the digital input signal is modulated with information, the RFID reader filters the analog input signal to produce a filtered analog input signal and transmits the filtered signal. When the digital input signal is an unmodulated signal, the RFID reader bypasses the filtering of the analog input signal to produce an unfiltered analog input signal and transmits the unfiltered analog input signal. |

1. A method for transmitting a signal by a Radio Frequency Identification (RFID) reader, the method comprising:
receiving a digital input signal; converting the digital input signal to an analog input signal; determining whether the digital input signal is an unmodulated signal or is modulated with information; when the digital input signal is modulated with information, filtering the analog input signal to produce a filtered signal and transmitting the filtered signal; and when the digital input signal is an unmodulated signal, bypassing the filtering of the analog input signal to produce an unfiltered analog input signal and transmitting the unfiltered analog input signal. |
