🔍 Key Concepts

• Phase-locked loop (PLL) as a feedback control system • Typical internal blocks of a PLL used in communications and navigation electronics • Difference between phase detection and other types of detection (like ratio detector or amplitude detector)

💭 Think About

• Which choice actually mentions a feedback loop that compares the phase of an input signal with a locally generated signal? • Look for the option that includes the three classic building blocks found in most PLL block diagrams in radio/communications texts. • Eliminate any answers that clearly describe unrelated circuits, such as one-shots (monostable) or simple amplifier stages rather than a phase-control loop.

✅ Before You Answer

• Verify that the correct answer includes a phase detector, not just any generic detector. • Check that the loop uses a voltage-controlled oscillator (VCO) whose frequency/phase can be adjusted by the loop. • Confirm that a filter element is present to smooth the control signal in the feedback path.
