A Method of Removing Bias Error in Convolution Numerical Calculation |
| |
| Abstract: | The convolution of the signal which has a beginning but no end will bring error including biaserror,approximation error and rounding error as calculating with digital computation method,in which bias error is a greater one generally.The bias error can be removed in the relative interval as the signal length is selected properly. |

| Keywords: | convolution numerical calculation bias error zero-order error |
