Impulses in the continuous and discrete worlds
The mathematical concept of an impulse is widely utilized in many disciplines, including physics, electricity, optics, etc. It is used to represent entities that are concentrated in a single point, such as a point mass, a point charge, etc. Although such entities do not exist in the real world, this theoretical concept is very useful since it may considerably simplify derivations [Bracewell86 Chapter 5; Brigham88 Appendix A].
