← ScienceWhich consequence results when impedance discontinuities increase within a terrestrial microwave communication link?
A)Increased reflected signal power✓
B)Better forward error correction
C)Higher SNR at receiver
D)Decreased incident wave velocity
💡 Explanation
Increased impedance discontinuities causes greater signal reflections because the changing impedance obstructs effective wave propagation, stimulating Fresnel reflection. Therefore, more power reflects back, rather than transmitting forward, differing from ideal scenarios without impedance changes.
