Network transmission impairments can degrade or corrupt signals and introduce bit errors. Attenuation causes signals to weaken over distance depending on the transmission medium. Delay distortion occurs for guided media where propagation speed varies with frequency. Noise such as thermal, intermodulation, crosstalk, and impulse noise from external sources can also be introduced that interferes with the original signal.
