Which limiting outcome occurs due to parasitic capacitance in high-speed digital signal transmission along circuit board traces?

A)Reflected waves causing signal distortion
B)Increased power dissipation as heat
C)Electromagnetic interference with nearby circuits
D)Reduced signal rise time

💡 Explanation

When signals propagate at high speeds, parasitic capacitance caused by trace geometry results in an RC delay because the capacitance must charge and discharge, slowing down the signal transition. Therefore a reduced signal rise time is the consequence rather than reflection, dissipation, or interference, which stem from impedance mismatches, resistance, and radiation, respectively.
