Eleven Causes for Line Noise
5. Attenuation is the loss of power a signal suffers as it travels from the transmitting device to the receiving device.
- as the signal becomes weaker the receiving device has less and less change correctly interpreting the data
6. Attenuation distortion refers to the fact that high frequencies lose power more
rapidly than low frequencies during transmission
(unequal loss of component frequencies)
7. Delay distortion refers to the distortion that occurs because different frequencies travel at slightly different speeds (bits transmitted at one frequency will travel slightly faster than bits transmitted at another frequency)
