In the context of signal processing it is often referred to as the unit impulse function. Note that the Dirac delta is not strictly a function. While for many purposes it can be manipulated as such, formally it can be defined as a distribution that is also a measure .
在物理上,通常用于代表脉冲函数,或者呈点分布的物理量,例如质点、点电荷等;另外,delta函数常用于表示对物理量在某点的抽样,这一点不仅在数学物理方法这样的理论学科中常用,在实际的工程通信中也很常用,这时delta函数被用作采样函数。
