In summary, the Dirac Delta function, also known as the impulse function, is a mathematical function commonly used in physics and engineering to represent point forces or masses. It is defined as a function that is equal to zero everywhere except at a single point and has various properties such as symmetry, scaling, sampling, and integration. In signal processing, it is used to represent a unit impulse and is often utilized in the analysis of systems and their responses to input signals.
