WebThe idealized impulsive forcing function is the Dirac delta function * (or the unit impulse function), denotes δ(t). It is defined by the two properties δ(t) = 0, if t ≠ 0, and ∫ ∞ −∞ δ(t)dt=1. That is, it is a force of zero duration that is only non-zero at the exact moment t = 0, and has strength (total impulse) of 1 unit. WebIt has the property that the energy or the area under the pulse is equal to one. This is expressed as. Thus, a weighted or scaled impulse function would be defined as one that satisfies. The weighted impulse function is drawn diagrammatically as an arrow with a height proportional to the scaling factor.
