← ScienceWhich outcome results when parasitic capacitance couples two traces?
A)Increased signal crosstalk interference coupling✓
B)Decreased characteristic line impedance matching
C)Reduced thermal noise floor stability
D)Improved power supply ripple rejection
💡 Explanation
Increased signal crosstalk occurs because capacitive coupling creates unwanted signal paths via electromagnetic induction, therefore energy transfers between traces rather than attenuating noise. Improved ripple is incorrect because decoupling occurs under power fluctuations; characteristic impedance mismatches are due transmission issues.
