← TechnologyWhich risk increases when impedance mismatches occur in a high-frequency transmission circuit?
A)Signal reflections and power loss✓
B)Increased capacitive circuit loading
C)Reduced operational amplifier bandwidth
D)Dominant common-mode noise coupling
💡 Explanation
Signal reflections and power loss increase because impedance mismatches cause a portion of the signal to reflect back to the source, a phenomena called "Reflection". Therefore, the effective transmitted power decreases, rather than improving signal qualities, as these require managed characteristic impedance.
