← TechnologyWhich signal degradation occurs when high-frequency transmission encounters impedance mismatches in coaxial cable?
A)Signal reflection and standing waves✓
B)Increased capacitive coupling
C)Enhanced signal transparency
D)Reduced dielectric constant variation
💡 Explanation
Signal reflection emerges at impedance mismatches due to a change in characteristic impedance along the transmission line causing some of the signal to bounce back rather than propagate forward because of impedance discontinuity. Therefore reflections and standing waves emerge, rather than capacitive coupling due to impedance.
