All is there.
I read your article siteBut it is difficult to me to understand itCan you write me in shortly an in easy way what it mean
FM stereo uses a form of time-share multiplexing. It first samples the left channel for 1/38,000 second, then the right channel for 1/38,000 of a second. A standard FM reciever with no stereo decoder will receive both channels and ignore any stereo information. The original reason for using this method, in fact, was to make it "listenable" on monaural receivers.
In order for a stereo receiver to "sort out" the left and right slices, a pilot signal, at exactly half the switching frequency (19KHz) is inserted in the signal. The receiver locks onto this pilot signal which then is used to synchronize the demultiplexer in the receiver...sending all the altenate left slices to the left channel and the alternate right slices to the right channel.
Hope this helps.
Your answer helps me a lot
But I need more help
Yet I don't understand all this problem
In Google, enter FM Stereo Theory.
Of course I used and will use google
But I yet don't understand it
beacause of this I ask for help in this forum
