Which outcome increases when a Phase-Locked Loop's (PLL) VCO unlocks due to a disturbance?

💡 Explanation

Spurious signals increase because the PLL's loop filter cannot track rapid phase changes resulting from VCO unlock via its phase detector; VCO instability creates sidebands, therefore more harmonics become present, rather than power rejection improving by design.
