The u it is a ba d- pass filter or a h igh-pass filters, it ca elmi i ate dy am icm easurem e t errors, but cause severe oise amp lificatio . I order to solve this prob- lem, a real-tmi e w avelet de- oisi g algorithm is researched i com pe sati g for dy am icm easurem e t error. The co- efficie cy of the u it is obtai ed via expermi e tal data, at the sam e tmi e, the real-tmi e w avelet de- oisi g algorithm that has the adva tages of off- li e w avelet de- oisi g algorithm is form ed through the orthogo al w avelet w ith com- pact support a d m ovi g w i dow. The m ethod is proved effective by the s mi u latio expermi e tal results of th i -film thermocoup le dy am ic error compe satio .
