Reading time: <1 minut Distortion and noise are two different unwanted effects on signals. The systems are designed to minimize the effect of these two unwanted phenomena. In data communication, if not properly addressed, the effects of attenuation and distortion have the potential to make a data transfer unsuccessful.
