What is linear discrete time system?
A discrete-time linear system is a way of grouping the dynamics of a particular model into a standardized matrix-vector equation. It requires you to separate variables into state (in our case, the position and velocity of the ice block) and controls (the force from the fan).
Is the discrete system linear?
It essentially means that the signal can start any time, the output remains the same but with the same delay as the input. For this course, we will always assume that the discrete time system is linear, shift- invariant. When building a linear discrete time system, we use only THREE operators: 1.
What is the example of discrete system?
A discrete system is one in which the state variable(s) change only at a discrete set of points in time. E.g. customers arrive at 3:15, 3:23, 4:01, etc. A continuous system is one in which the state variable(s) change continuously over time. E.g. the amount of water flow over a dam.

Superposition Principle
Hence, we can say that a system is linear if the output of the system due to weighted sum of inputs is equal to the weighted sum of outputs. Filter circuits, communications channels, etc. are few examples of linear systems.
