I want to know the format of FM radio signal, how it is modulated from microphone to RF and how it is demodulated from RF to speaker? Could you give some reference book on this topic?

Thanks very much.

Back in the day, FM stereo was pretty cunning. Now one looks at its limitations (poor dynamic range, 14 KHz audio rolloff, etc) and it looks pretty crude.

Your question is about principle of FM modulation/demodulation and this link will give you the answer:

About FM Stero transmissions. I think today there are no more then 1% of DAB, RDS, etc, from total radio users. Standard Stereo FM will be in place for many years now on, even if we are sick of it.

You can read Razavi's RF Microelectronics or Thomas Lee 's book
