C)variable inductance.
D)phase detection.

Question

Quizplus · Accepted Answer

VCOs (Voltage-Controlled Oscillators) used in PLLs (Phase-Locked Loops) typically operate on the principle of variable reactance, where the input voltage changes the reactance in the circuit, thereby altering the oscillation frequency.
