Dirac delta function is a mathematical concept used in the field of signal processing and mathematics that represents an idealized point function.
Dirac delta function is often denoted by the symbol δ(t) and is defined as zero everywhere except at t=0, where it is infinite, yet integrated over its domain is equal to one.
Properties of Dirac Delta Function
Dirac delta function is used to model impulses or sudden changes in certain physical phenomena, such as voltage spikes in electrical circuits or shockwaves in fluid dynamics.
It is a distribution, not a traditional function, meaning it does not have a classical function definition but instead is defined through its behavior under integration with test functions.
Applications of Dirac Delta Function
Dirac delta functions are commonly used in physics, engineering, and mathematics to simplify calculations and models involving impulse-like phenomena.
The Laplace transform of a Dirac delta function is always equal to one, making it a useful tool in solving differential equations and signal analysis problems.
