Abstract: A signal encoding apparatus and method of a radio frequency identification (RFID) reader capable of removing a high frequency component without using a digital filter, and performing Manchester encoding by using two symbols. The signal encoding apparatus of the RFID reader including an encoding unit that stores a first symbol and a second symbol; transmits the first symbol if data received after an initial state is zero (0), and returns to the initial state; delays for a given time period if the data received after the initial state is one (1); transmits the second symbol if data received after the delayed given time period is zero (0), and returns to the initial state; and transmits the first symbol if the data received after the delayed given time period is one (1), and stands by.

Abstract translation: 一种能够在不使用数字滤波器的情况下去除高频分量并且通过使用两个符号执行曼彻斯特编码的射频识别（RFID）读取器的信号编码装置和方法。 RFID读取器的信号编码装置包括存储第一符号和第二符号的编码单元; 如果在初始状态之后接收的数据为零（0），则发送第一符号，并返回到初始状态; 如果在初始状态之后收到的数据是1（1），给定时间段的延迟; 如果在延迟的给定时间段之后接收到的数据为零（0），则发送第二符号，并返回到初始状态; 并且如果在延迟的给定时间段之后接收到的数据是一（1）并且等待，则发送第一符号。
