This paper introduces the basic structure of FIR digital filters, on the discussion of the design method of FIR digital filters, and points out that the traditional based on the design method of digital filter process is complicated, computing workload big, filtering properties is hard to adjust the insufficiency, was proposed based on the Matlab software of digital filter design method. FIR digital filters can be strictly linear phase, mainly adopts the recursive structure, no matter from the theory or in actual limited precision operation does not exist stability problem, computation by the error of the output signal noise power is small. In addition, FIR digital filters can use FFT algorithm, in the same order number, under the condition of speed can be greatly improved, are widely used in image signal processing, data transmission, etc. To carry signals wave system.

v列子·说符》:“昔齐人有欲金者,清旦,衣冠而之市,适鬻金者之所,因攫(jue,抓取,抢夺)其金而去。吏捕得之,问曰:‘人皆在焉,子攫人之金何?’对曰:‘取金之时,不见人,徒见金。’”
释译:从前齐国有个想得到金子的人,一天清早,穿好衣服,戴好帽子,来到集市上,走到卖金子的地方,抓了金子就走。巡官抓住了他,问他:“人们都在场,你怎么敢抢人家的金子呢?”那人回答说:“我抓金子的时候,根本没看到人,只看到金子
