FIR 滤波器的结构主要是非递归结构, 没有输出到输入的反馈。并且FIR 滤波器很容易获得严格的线性相位特性, 避免被处理信号产生相位失真。FIR数字滤波器是数字信号处理的经典方法,其设计方法有很多,通常使用窗函数法,借用MATLAB程序设计语言对FIR数字滤波器进行仿真,所产生的滤波器系数可以直接倒入DSP中进行编程,用DSP汇编语言实现该FIR滤波器在编程时候可以采用DSP独特的循环缓冲算法对FIR数字滤波器进行设计,这样可以大大减少设计的复杂度,使滤波器的设计快捷,简单。实践证明,该滤波器准确度高,稳定性好,易于移植使用,具有较强的实用性与灵活性。用可编程DSP芯片实现数字滤波可通过修改滤波器的参数十分方便地改变滤波器的特性。

FIR filter structure main right and wrong recursion structure, Has not output the input the feedback. And the FIR filter are very easy to obtain the strict linear phase characteristic, Avoids processing the signal to produce the phase distortion. The FIR numeral filter are the digital signal processing classical method, its design method has very much, usually uses the window function method, borrows the MATLAB programming language to carry on the simulation to the FIR numeral filter, produces the filter coefficient may pour into in DSP to carry on the programming directly, realizes this FIR filter with the DSP assembly language at programming time may use the DSP unique circular buffering algorithm to carry on the design to the FIR numeral filter, like this may reduce the design greatly the order of complexity, causes the filter the design to be quick, simple. The practice proved that, this filter accuracy is high, the stability is good, easy to transplant the use, has the strong usability and the flexibility. May through revise the filter with the programmable DSP chip realization numeral filter the parameter to change the filter extremely conveniently the characteristic.

The structure main right and wrong of FIR filter passes to return structure, there is no the feedback which outputs an importation.And the FIR filter acquire strict line very easily mutually characteristic, avoiding being handled signal to produce mutually to lose really.The FIR numerical filter is the classic method that the numerical signal handles, its design method has a lot, usually using a window function method, using MATLAB program design language to the FIR numerical filter carry on imitating really, the filter coefficient produced can pour in to be in the DSP carry on weaving a distance directly, with the DSP edit collected materials the FIR's filter of the language realization Be weaving a distance can adopt the DSP special circulating buffer calculate way to carry on a design to the FIR numerical filter for time, so can reduce complications of[with] design consumedly, make the design of filter fast, simple.Practice a certificate, that filter the accurate degree is high, stability good, be easy to transplant an usage, have stronger function and vivid.Filter wave with the programmable DSP chip realization numeral can pass to modify a filter of the parameter changes the characteristic of filter very expediently.

The structure main right and wrong of the filter of FIR passes to return the structure, didn't feedback that output the importation.And the filter of FIR acquires the strict line very easily mutually a characteristic, avoid to be handle the signal creation mutually really lose.The numerical filter of FIR is the classic method of the numerical signal processing, it designs the method to have a lot of, usually use the window function method, use the MATLAB program design language to carry on imitate to the numerical filter of FIR really, the filter coefficient produce can pour into directly in the DSP carry on weaving the distance, with the DSP edit collected materials the language realization FIR's filter at weave the distance for time can adopt the special and circulating buffer calculate way of DSP to carry on the design to the numerical filter of FIR, thus can reduce complications of design consumedly, make the design of the filter fast, simple.Practice the certificate, the accurate degree of that filter is high, stability good, be easy to transplant the usage, have the stronger function and vivid.Carry out the numerical wave of 滤 can pass to modify the filter with the programmable chip of DSP of parameter change the characteristic of the filter very and expediently.
