| Abstract: | A new method which is called the Pattern Filter Theory(PFT) was introduced in this paper.Applying it to process signal of tractor engine,signals and noises could be integrally and reasonably separated.The study provided the foundation to effective reduction of the tractor engine noises and theoretical reference to study on fault diagnosis of tractor engine. |
