| Abstract: | The computational methods of convolution have extremely extensive application in the fieldsin signal processing and system theory and other relational fields.The key of convolution computationis how to determine the integral limit(or determine the sum limit).This paper gives an effective anddefinite method by analyzing the operation of convolution integral.The method solves the problem ofrepetition and pretermission of the integral limit(or determine the sum limit)in computational pro-cess. |
