(1) Filter synthesis 12.1 Introduction An ideal filter would perfectly transmit signals at all desired frequencies and completely reject them at all other frequencies.

(2) The simulation results reached nearly ideal filter characteristics, and the performance of removing image noise using this filter was compared with the median filter.

(3) Besides, we consider the ideal filter group's delay may be equal to it's order.

(4) Fiber filter with its excellent performance and the "ideal filter layer" of bed structure, in practical applications show a huge advantage, and gained rapid development.

(5) Electret air filter material has superior filter performance, as ideal filter material for coal - dust stained yarn.

(6) The cigarette filter tip rod has the advantages of reasonable structure and good filtration effect, and is an ideal filter tip rod for low-tar and ultra low-tar cigarette products.

(7) Super fine fiber have excellent filter efficiency and low resistance, it is ideal filter materials in producing medical protective mask, protective clothes and positive pressure fi...

(8) Use:It uses in professions and so on oil field, smelting, environmental protection chemical industry, is the oily sewage processing ideal filter material.
