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).
Advantages[]
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[]
Disadvantages of Digital are:
- Sampling Error
- Require greater bandwidth than analogue to transmit the same information.
- Requires the communications system to be synchronized.
