CONTINUOUS TIME AND DISCRETE TIME SIGNALS (C.T. AND D.T. SIGNALS) | Examples and Signal Diagrams

What is a Signal?

Definition of Signal 

A signal may be defined as a function of one or more independent variables like time, distance, position or temperature etc., that has some information about the phenomena that produced the signal.

So in other words we can say, a signal is a function of independent variables having some information.
The signals maybe motion signals, sound signals, image signals or video signals etc.

Signals can be classified into two types based on their characteristics in time domain-
Continuous Time Signals (C.T.)
Discrete Time Signals (D.T.)

Continuous Time Signals (C.T.)

A signal that is defined continuously with independent variable (time) is called a continuous time signal.
