<P>PROBLEM TO BE SOLVED: To obtain more natural sound quality in receiving audio through digital communication by wireless. <P>SOLUTION: A digital radio receiver (1) comprises: a demodulation circuit (10) which receives and demodulates a high-frequency signal (101), and converts the signal into a digital signal (102); a decoding circuit (20) which decodes the digital signal (102) to obtain encode data and decodes the encode data to convert the data into an audio signal (103); a noise-extraction circuit (30) which obtains a noise signal (104) from the digital signal (102); and an adder (40) which synthesizes the noise signal (104) and the audio signal (103). <P>COPYRIGHT: (C)2013,JPO&INPIT |
