A jump discontinuity in a step function occurs when the function's value abruptly changes at a particular point, creating a "jump" between two different constant values. This sudden change happens when the definition of the function switches from one interval to another within the piecewise function.

For example, in the Heaviside step function $H(x)$, the function jumps from 0 to 1 at $x = 0$
