Digital Vs. Analog

Why Digital Signals are Better

By Xavier Ameling

What are Analog Signals?

Analog signals are the original signals, which are traditional transverse waves that are easily interfered with. These are used when you speak, or listen to music for example.

Digital?

Digital is a different type of wave, while still basically the same. It is still a transverse wave, but instead of arcs of sound, the position is either "on" or "off", making it much harder for noise to interfere with the wave, making it a much cleaner sound. These signals are used when using your phone, television, or computer.

Here is an Example

Music used to be recorded on records, discs that stored the actual analog waves in the material itself, by engraving. When the CD (Compact Disk) came out, it was the first digital source of audio. The record was still better for quality, but if used extensively, it loses its quality. The CD will not.

Why Analog is Used

Analog is very good for short distance communication, such as AM Radio or a conversation. Gradually over space, or when interrupted by noise like a jackhammer, the quality may fade. Everyone uses these waves, when you talk or watch TV for example.

Why Digital Is Used

Digital is good for any distance, and isn't as easily interrupted by interference. Some examples of digital waves are cellphones and MP3 players. These waves are mainly used by people when someone they use an electronic device.
