← ScienceWhich risk increases when signals propagate through a lossy dielectric waveguide?
A)Increased signal amplitude integrity
B)Reduced waveguide characteristic impedance
C)Elevated multipath interference strength✓
D)Decreased group velocity stability
💡 Explanation
Increased multipath interference occurs because signal degradation in the medium reflects more strongly off imperfections triggering stronger, unintended waves; therefore stronger interference results rather than signal fidelity due to signal weakening.
