#113 In this video I start looking at Phase Locked Loops, or in short PLL's. Now to brake down the topic into more manageable parts, today I will only look at the phase detector that can be implemented with digital logic gates. I look at what the operating principle behind this is then I try things out in the circuit simulator and finally in real life.
