Good day to all of you, guys.

I'm a newbie in communications and I do have some questions I hope you can help me answer. Maybe if you have time, I would really appreciate it.

Thanks in advance! 🙂

1. Give 5 other uses of FM broadcasting and discuss how FM is being used.

2. Why do we say that FM stereo broadcasting is using a Frequency Division Multiplexing? Explain.

3. Why is 19 kHz used as the carrier frequency of the FM stereo broadcasting, why not other frequencies?

Hi John,

These questions sound like they might be from a textbook or from a class lecture, is that correct?  If it is for a class, we don't want to impede the learning process by answering the questions directly.  What research have you done/what articles have you read about FM?  I would recommend doing some of your own research online, but here are two articles that may be of use to you:

Wikipedia: Frequency Modulation

http://en.wikipedia.org/wiki/Frequency_modulation

Wikipedia: Orthogonal Frequency Division Multiplexing

Thanks,
