Bandwidth

From Simple English Wikipedia, the free encyclopedia

Bandwidth is a measure of how much information can go through a system. There are two different cases:

  • Analog signals
  • Digital signals
The bandwith (of passing through the x-axis twice)
The bandwith (of passing through the x-axis twice)

Analog Signals have the form of an electromagnetic wave. They go up and down. At some point, they pass an axis of symmetry. This is called the x-axis. The bandwidth of an analog signal is simply the distance between two such traversals through the x-axis. This rate is measured in Hertz.

In digital systems, there is no signal in wave-form. In those systems, the bandwidth is measured in baud, and stands for the signal rate.
