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.
