← ScienceWhich electromagnetic wave outcome reduces signal integrity in high-speed digital circuits?
A)Reflections caused by impedance mismatch✓
B)Attenuation due to dielectric absorption
C)Diffraction around circuit components
D)Refraction across conductor interfaces
💡 Explanation
Signal integrity decreases because impedance mismatch causes signal reflections, leading to superposition via the stationary wave propagation mechanism. Therefore, reflections are the primary concern in digital circuit design, rather than dielectric absorption or diffraction, which are secondary effects.
