Noise, cross-talk, and other forms of interference are a significant issue in any communications infrastructure.

Noise, cross-talk, and other forms of interference are a significant issue in any communications infrastructure. Compare and contrast how this problem would manifest for analog data transmitted with an analog signal, for analog data transmitted with a digital signal, for digital data transmitted with an analog signal, and for digital data transmitted with a digital signal. Be sure to compare the quality of the resulting communication as well as the physical description
