#118 In this video I look at one of the main use cases for PLL circuits in RF applications which is the demodulation of FM signals. I will be looking at how this sort of circuit works and how the elements need to be designed to get optimum performance. In the end I build a PLL demodulator and perform some experiments and measurements.

More on PLL's:
Frequency multiplication: youtu.be/VqcMGULfPjg
FM demodulation: youtu.be/d6ufJtyX6XA
The Phase Detector: youtu.be/uTaZ6uL1t-U
The VCO: youtu.be/JjoO59CY_UQ
