← ScienceWhich outcome initiates electromagnetic interference when a crystal oscillator operates beyond capacitance limits?
A)Spurious harmonic frequencies increase substantially✓
B)Resonance stability shows minimal fluctuation
C)Temperature dependence is effectively mitigated
D)Phase noise demonstrates significant improvement
💡 Explanation
Spurious harmonic frequencies increase because parasitic impedances affect resonant behavior initiating harmonic distortion via mode coupling rather than damping, therefore resulting in EMI increases rather than noise reduction or stability because stability and temperature controls are overwhelmed due to excessive currents.
