A linear model represents an accurate representation of the behavior of many systems where the non-linear system has steady state performance with a different kind of behavior. Here this article gives the information about the example of a linear and nonlinear system to know more details about it.
Example of linear systems :
- Electronics circuit such as amplifier
 - The unity system, where the output of a system is always equal to the input
 - Multiplication by a constant that is the amplification of the system
 - Linear system where the wave propagation produce such as sound as well as an electromagnetic wave
 - Some electrical circuit composed of the resistor, capacitor, and indicator
 - The null system where the output is always equal to zero regardless of the input system
 - Differentiation and integration
 - A signal must be changed such as a resonance and image blurring
 - A mathematical operation like a convolution where each value in the output is expressed as the sum of values in the input multiplied by a set of some weighing coefficient, so here give some many more example of linear as well as a non-linear system
 
Example of a non-linear system :
- A system that does not have sinusoidal fidelity such as electronic circuit
 - Common electronic distortion clipping and cross over distortion
 - Saturation such as an electronic amplifier and transformer are driven too hard
 - A system does not have static linearity
 - A system with a threshold like digital logic gates
 - Multiplication of signal by another signal called as amplitude modulations
