Application of Wavelet Transform in Signal Filtering
-
摘要: 概要地敘述了小波、小波包理論,提出了一種用小波包分解和信號重構進行信號濾波的方法.先用小波包分解把信號分解到相鄰的不同頻率段上,然后用信號重構方法對各個頻率段上的信號進行重構.以電機的振動信號為例,說明這種方法可以有效地用于信號的濾波.Abstract: A new method of signal filtering with wavelet packets and signal reconstruction is proposed.At first, signal is decomposed in different frequency bands, and then the signal of each frequency band is reconstructed. By analyzing the vibration signal of a motor, this method is applied in signal filtering successfully.
