← ScienceWhich constraint affects a digital signal cutoff frequency?
A)Transmission line characteristic impedance matching✓
B)The gain of transistor amplification
C)Antenna polarity in radio frequency
D)Refraction index medium alteration
💡 Explanation
Signal integrity degrades due to impedance mismatches which cause reflections, thus transmission line matching impacts cutoff frequencies, because it minimizes signal reflections resulting in clearer signal propagation across frequency ranges; therefore mismatched cables create lower effective bandwidth, rather than gain limitation.
