DEVICE AND METHOD OF DEMODULATING SIGNAL

摘要

A method and an apparatus for demodulating a signal are provided to reduce power consumption of a receiver by demodulating an input signal having a high frequency through a demodulator having a simple structure. A phase detecting part(610) detects phase information of an input signal based on a sampling result about the input signal modulated as a carrier wave having a first frequency. A clock generating part(620) generates a clock signal having a demodulation frequency which is synchronized with the input signal by the phase information. A sampling part(630) samples the input signal in response to the generated clock signal. The sampling part samples the input signal in a time in which a rising edge and a falling edge of the clock signal are generated. A demodulating part(640) demodulates the input signal based on a sampling result of the sampling part.
