← ScienceWhich phenomenon reduces transmitted signal clarity in high-frequency PCB traces?
A)Skin effect losses increase impedance✓
B)Dielectric absorption slows propagation
C)Faraday shielding induces eddy currents
D)Capacitive coupling introduces impedance bridges
💡 Explanation
The skin effect concentrates current near the conductor's surface, because higher frequencies experience greater self-induction pushing current flow toward the periphery. Therefore, effective resistance increases, raising impedance and signal loss, rather than the other options which also affect signal integrity.
