← ScienceWhich signal distortion happens to high-frequency signals propagating through transmission lines due to frequency-dependent velocity?
A)Chromatic Dispersion broadens rapidly✓
B)Inter-symbol Interference reduces sharply
C)Code Division Multiplexing increases
D)Frequency Modulation enhances fidelity
💡 Explanation
Chromatic Dispersion broadens the pulse width because pulse velocity varies with frequency; therefore higher frequencies arrive delayed compared to lower frequencies, rather than signal enhancement occurring because each frequency component travels at different speeds.
