摘要：
A rapid high-precision measurement of distorted power is described. It is based on digital filtering techniques. The convergence conditions of two previous sampling algorithms are derived, and their frequency responses are analyzed. A new adjustable window used for measuring distorted power is proposed. It is demonstrated that the sampling algorithm using the new window leads to significant savings in measuring and computing time, and a high accuracy can be obtained.
