Delta function approximation
Delta function approximation refers to methods used to model the Dirac delta function, which is a mathematical tool that represents an idealized point source or an instantaneous event. Since the true delta function is infinitely sharp and cannot be directly used in calculations, approximations create very narrow, high peaks that mimic its behavior. These approximations allow engineers and scientists to work with functions that concentrate energy or effects at a specific point or moment, facilitating analysis and computation in fields like signal processing, physics, and engineering.
