Which outcome occurs when a radio transmitter's phase-locked loop (PLL) loses lock?

💡 Explanation

Loss of PLL lock in a radio transmitter causes spurious signal frequency transmissions because the frequency synthesizer operates unstably, therefore injecting unwanted frequencies into the output rather than a clean, stable carrier.

• Which phenomenon leads to reduced control sensitivity when hydraulic spool valve orifice edges become rounded?
• Which risk increases when engine piston-to-cylinder clearance exceeds design tolerance?
• Which microstructural effect causes embrittlement in forged alloy components at elevated temperatures?
• Which mechanism causes stick-shaker activation during powered flight near stall?
• Which effect occurs when a proportional valve undershoots rapidly in a hydraulic actuator system?
• Within a hydraulic actuator driving a robotic arm, which consequence results when the spool valve's sharp edges erode due to fluid impingement?
