Definition

A step function is a piecewise-defined function that jumps from one constant value to another at specific intervals. It resembles a series of steps on a staircase.

Piecewise Function: A piecewise function is defined by different formulas or rules for different parts of its domain. Step functions are an example of piecewise functions.

Heaviside Function: The Heaviside function is a specific type of step function that equals zero for negative inputs and one for positive inputs.

Discrete Function: A discrete function takes on distinct values rather than forming continuous curves. Step functions are examples of discrete functions due to their abrupt changes in values.
