Which constraint limits signal propagation distance in unterminated coaxial cables?

💡 Explanation

Reflections distort the signal wave because impedance mismatches at cable ends cause signal reflections via constructive/destructive interference, therefore signal clarity degrades over distances rather than simple uniform attenuation by losses if properly terminated.
