Which mechanism increases RF noise floor when PCB trace impedance mismatch?

A)Capacitive parasitic oscillations
B)Inductive coupling feedback
C)Transmission line resonance
D)Thermionic emission amplification

💡 Explanation

Because impedance mismatches create reflections, energy is trapped, exciting parasitic capacitance on traces initiating spurious oscillations; a form of EMI. These oscillations introduce unwanted frequencies, therefore noise increases rather than resonance, which requires specific trace lengths.
