A Nicety Evaluation Method of Sine Wave Phase Difference
Shen Xiaofeng · Measurement & Control Technology · 2008
Counting on the deficiency of practical application in sine-wave fitting method,a new method,sine-wave convergence curve-fit arithmetic to estimate delays between channels in data acquisition system is introduced.The causation of delays between channels,the source of error in estimation process,computer simulation and testing results about estimation process are also discussed.Simulation and testing results prove that this arithmetic has a high veracity and practicability in estimating delays between channels in data acquisition system.
