SIGNAL PROCESSING APPARATUS FOR RECEIVING RFID SIGNAL AND METHOD THEREOF

摘要

A signal processing apparatus for receiving RFID signal comprises a first low-pass filter, a first down-sampler, a first comparator and a first waveform converter. The first low-pass filter filters the RFID signal. The first down-sampler down-samples the filtered RFID signal. The first comparator generates a new signal for value determination according to the down-sampled RFID signal. The first waveform converter converts the waveform of the new signal for the following process.
