Which limitation arises when impedance mismatch impedes signal propagation?

A)Increased signal reflection losses
B)Decreased power supply efficiency
C)Elevated transistor junction temperatures
D)Diminished electromagnetic interference shielding

💡 Explanation

Signal reflection losses rise because impedance mismatch disrupts effective energy transfer through the transmission line; therefore, less power propagates forward, resulting in greater reflections, rather than affecting efficiency or shielding, which pertain to different mechanisms.
