## Dirac Delta Function: Also known as

The **Dirac delta function** is less commonly rendered as **Dirac's delta function**.

It is also called the **unit pulse function** or **unit impulse function**.

Some sources refer to $\map \delta x$ just as the **impulse function**.

Some, acknowledging the fact that it is not actually a function as such, refer to it as the **unit impulse**.
