In color television, another PLL makes sure green remains green and red remains red (even if politicians claim the reverse is true). A PLL is a circuit that causes a particular system to track with another one. More precisely, a PLL is a circuit synchronizing an output signal (generated by an oscillator) with a reference or input signa…
