Shouldn't the output of an FM PLL demodulator (for a receiver) be the message signal? everywhere I look online, it says that the output is a modulated signal. What is the point of having a modulated signal at the output when you're trying to demodulate the FM signal? I look at all the other discriminator circuits, such as Slope detector, or Foster Seeley discriminator, which are more comprehensible, but what is the PLL accomplishing from demodulating an FM signal, when everyone is saying that the output is a modulated signal?
