Application of Elliptic Digital Filter in Dynamic Wind Tunnel Test
Tong Sheng-xi · Aeronautical Computing Technique · 2011
An advanced data processing method is demanded,because there are more noises in the raw data of dynamic wind tunnel test,compared with the static wind tunnel test.The characteristics of dynamic wind tunnel test data and the difference of various digital filters are analyzed,and the elliptic filter is the selection.The numerical computing method of elliptic functions and the design process of the elliptic digital filter are discussed in this paper.An instance is demonstrated which is designed for a research project,and the result was satisfying.
