Number Systems - Signals and Different Types of Signals

Introduction:

In the Modern World of electronics, the term "digital" is generally associated with a computer.
This is because, the term "digital" is derived from the way computers perform operation, by counting digits.
For many years, the main application of digital electronics was only in the Computer systems.
But today, the digital electronics is used in many other applications such as : TV, Radar, Military systems, Medical equipment's, Communication systems, Industrial process control and Consumer electronics.

Signals:

Define Signal?

We can define "signal" as a physical quality, which contains some information and which is a function of one or more independent variables.

Different Types of Signals :

The signals can be of two types:

1. Analog signals

2. Digital signals

Digital signals :

A digital Signal is defined as the signal which has only a finite number of distinct values. Digital signals are not continuous signal. They are not continuous signal. They are discrete signal bellow.

Binary signal (Digital signal)

Binary signal : If a digital signal has only two distinct values, i.e. 0 and 1 then it is called as a binary signal.

Octal signal : A digital signal having eight distinct values is called as an octal signal.

Hexadecimal system : A digital signal having sixteen distinct values is called as the hexadecimal number.

 

Types of digital signal	Number of distinct values
Binary	2
Octal	8
Hexadecimal	16
