Which mechanism causes loss of signal integrity in a high-speed transmission line when impedance is mismatched?

💡 Explanation

When impedance is mismatched, signal reflections occur because the transmission line's characteristic impendance does not match the source or load, leading to standing waves which distort the data. Therefore signal integrity is lost by reflections, rather than by attenuation, crosstalk, or dispersion, which stem from separate mechanisms.
