The step response of a system is its output when subjected to a step input, which is a type of input signal that changes from one constant value to another constant value instantaneously. In control theory and signal processing, a step input is often represented mathematically as a unit step function, denoted as \\( u(t) \\). \#\#\# Key Aspects of Step Response: 1. **Definition**: The step response describes how a dynamical system reacts over time after a sudden change in input.
