Why is digital signaling more straightforward than analog signaling?
What will be an ideal response?
Digital signaling uses only two values: 0 and 1. These values are represented electronically. Because digital signals are one value or the other, with no variance in between, they are a discrete representation. This discrete representation means that digital signals have only a given, specific value. Digital signaling is usually less expensive than analog signaling because it requires less complex circuitry. Noise interference is less of a problem in digital signaling, making error detection and correction easier. A disadvantage is that digital signals are more susceptible to attenuation. This weakening of the signal is caused by friction. The longer the distance that a signal needs to travel though a circuit the more probable attenuation becomes. Different media, however, will suffer from attenuation at varying distances. Digital signals can be carried over copper or fiber-optic cables.
