← ScienceWhich consequence results when mismatched impedance causes signal reflections in coaxial cabling?
A)Decreased signal strength (attenuation)✓
B)Increased electromagnetic interference (EMI)
C)Elevated operating temperature limits
D)Spurious harmonics in downstream circuits
💡 Explanation
The *impedance mismatch* at cable joints reflects a portion of the forward signal back toward the source; because the power delivered to the load decreases with increased back reflection. Therefore, attenuation results, rather than other mechanisms influencing other phenomena.
