The relation between input and output of Linear Time Invariant System (LTI) can be expressed by _____.

a. Differential Equations
b. Impulse Response
c. Block Diagram & State-space representation
d. All of these

Correct Answer : d. All of these

Explanation :

Input-output relationship can be designated with an assistance of differential equations, impulse response, block diagram along with the state-space representation. All these functionalities / parameters are essential to define the input & output relationship for any LTI system.
