Digital Waveform Signal

A digital signal is the newest data technology that uses discrete (discontinuous) values. binary numeral system, or base-2 number system, represents numeric values using two symbols, 0 and 1. More specifically, the usual base-2 system is a positional notation with a radix of 2. Owing to its straightforward implementation in digital electronic circuitry using logic gates, the binary system is used internally by all modern computers.

Basically, a digital signal can only perform two logical operations or two states either: on (1) or off (0).


There are some advantages of Digital circuitry such as,

  • Less expensive
  • More reliable
  • Easy to manipulate
  • Flexible
  • Compatibility with other digital systems
  • No noise
  • Integrated networks


Disadvantages of Digital are:

  • Sampling Error
  • Require greater bandwidth than analogue to transmit the same information.
  • Requires the communications system to be synchronized.
