立体声广播是把左和右两个声道的信号,通过广播电台的发射机进行编码,然后用调频方式,向空间发射,接收机接收到这个电波后经过解调和解码,还原成左右两个声道的信号,供扬声器还原成立体声,重现声舞台。立体声广播与彩色电视广播一样,需要采用兼容制来传送,即用单声道接收机也能够接收立体声广播的信号,只不过听到的是单声道效果,声音没有立体 Stereo broadcasting is the signal of the left and right two channels, through the radio transmitter to encode, and then use FM mode, to the space launch, the receiver receives this wave after demodulation and decoding, reduced to about two The channel signal, for the speaker to restore stereo, reproduce the sound stage. Stereo broadcasts, like color television broadcasts, need to be transmitted using a compatible system, ie, monaural receivers are also capable of receiving signals from stereo broadcasts, except that they hear monaural effects without stereo sound
