Actually if we use a phase detector in the PLL, then we use LPF only to cut the transients that comes out from the detector along with a DC voltage that denotes the phase error.Because only when the control voltage to the VCO is stable, it can work properly.
If we make use of a Frequency detector instead of Phase detector, what would be the reason for using the LPF.
