【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.更多还原
