FM Remote Speaker System
A high quality, noise free, wireless FM transmitter/receiver may be made using
the LM566 VCO and LM565 PLL Detector. The LM566 VCO is used to convert the
program material into FM format, which is then transformer coupled to standard power lines. At the receiver end the material is detected from the power lines
and demodulated by the LM565, pdf file |
