I am trying to develop a PLL(Phase-locked loop) and want to use it to demodulate FM. But I am facing many problems.
1> I am not getting any practical circuit of PLL that can be implemented.
2> We then decided to implement the three components of PLL namely a)Multiplier, b)VCO and c)Low pass filter separately and then will combine them to form a PLL.
But again the problem is we are not getting any practical circuit of analog Multiplier that can be implemented in a PCB or breadboard.
second is we are not getting any idea how to implement the VCO with NE/SE566 chip.
pls help me if u can and give me an idea where i can find the tutorial where the mathematics is given so that we can carry it forward.
We are not developing any FM radio receiver, we are developing just a PLL to demodulate FM of low frequency. please help.
