DEMODULATION APPARATUS AND METHOD FOR OPERATING THE SAME

摘要

A demodulation device according to an embodiment of the present invention includes an envelope detection unit receiving a signal from the outside and detecting an envelope signal from the received signal; a reference voltage generation unit generating a reference voltage based on the detected envelope signal; a comparison unit outputting a pulse signal based on the envelope signal detected by the envelope detection unit and the reference voltage generated in the reference voltage generation unit; and an input signal control unit which is formed in an envelope signal input unit of the comparison unit and selectively controls the size of the envelope signal inputted in the comparison unit.
