Wavelet Transform for Thermal Analysis Signal
-
摘要: 用小波分析方法对热分析信号进行多分辨率分析,达到很好的滤波效果。经小波方法滤波后的热分析信号能有效地进行人工干预判峰或自动判峰,使研制的热分析仪性能有了很大提高。小波变换程序用VB语言实现,与热分析仪的操作环境融为一体。Abstract: Wavelet transform was used for thermal analysis signal to get multiresolusion, thus a good filtered thermal analysis signal was obtained. The start peak point,the end peak point of filtered signal can be set and the peak area can be calculated by automatic or manual manner easily. This method has been used in thermal analysis instruments. Wavelet transform was programmed by VB which was same as the other sorftware language in the instrument.
