Main Question or Discussion Point
I don't understand why a PLL alone can't be used as an FM receiver. I've got a project showing how PLLs are used and I'd like to use an FM transmitter (which I have a schematic for) transmitting wirelessly a signal that is demodulated by the PLL a few feet away. Seems pretty simple, where I set the lock range of the PLL to the desired level, an antenna to the input, and the PLL outputting the original signal. Why can't I just have a PLL followed by an amp to drive a speaker?
