← TechnologyWhich outcome occurs when a resonant circuit in a radio transmitter experiences parasitic capacitance at high frequencies?
A)Increased harmonic distortion in the output
B)Reduced power amplification efficiency
C)Elevated operating temperature in transistors
D)Unintended frequency drift in output signal✓
💡 Explanation
When a resonant circuit experiences parasitic capacitance because of unintended capacitive coupling in components, the resonance frequency shifts based on the formula 1/sqrt(LC), leading to unwanted frequency drift. Therefore, unintended frequency drift results, rather than distortion, reduced efficiency or overheating, which require different failure mechanisms.
