Hello, I'm a newbie in electriacal circuits.
I want to implement a power line communication based on frequency modulation. At this point I'm able to "inject" bursts over the power line, but I'm having serious problems acquiring the burst.
I'm working with a 24AC line, and microcontrollers. I don't need high baudrates, just a reliable way to comunicate and a high immunity to noise.
From what I've learned the best way to archive a high noise immunity is to use frequency modulated signals to trabsmit bits (correct me if I'm wrong please).
I would appreciate if someone could answer to some questions:
-Is there any IC which can detect a signal between 100kHz and 150kHz and return a proporcional voltage?
-Or is any IC which can detect a 125kHz signal and retrieve a logic one?
Thanks
