| 摘 要： | 针对先进飞机远程终端采样技术,对电压/电流(400Hz)采样点数和精度关系进行了讨论,由于工程采样中数字积分法的开方计算有效值对实时性有很大影响,给出了全新的不带根号的采样有效值算法,精度要求高的场合又在该算法的基础上设计了迭代算子. |
| 关 键 词： | 采样点数 精度 去根号算法 迭代算子 |

| Abstract: | To the electrical current and voltage(400Hz) in electrical remote terminal(ERT) in airplane,the relationship between the number of sampling points and sampling precision is discussed.Since the effect of computing virtual value with radical sign in engineering sampling arouses real-time characteristic,a new algorithm to avoid extraction is obrained.Furthermore,an iterative arithmetic operator based on this algorithm is put forward to improve precision. |
| Keywords: | number of sampling points precision algorithm of removing radical sign iterative arithmetic operator |
