Signal processing filter design is the core issue. As the finite impulse response (FIR) digital filter with infinite impulse response (IIR) digital filter is difficult to achieve linear phase characteristics, the signal transmission does not occur when significant phase distortion, thus FIR filter in engineering practice has been widely used. FIR filter is the core of the design of finite impulse response calculated to approximate the given frequency response, common design method is a window method and frequency sampling. In this paper, design of frequency sampling FIR filter, frequency sampling method can be directly in the frequency domain of the FIR filter design, for those who only a few selected non-zero value of the sampling frequency narrowband filter particularly effective. 】 【Body
A linear phase FIR digital filter characteristics:
1, the introction of the linear phase
Set for the FIR filter frequency response function. Can be expressed as
Called the rate function for the real function. It should be noted and the amplitude frequency characteristics of different functions for the positive real function, while the desirable negative.
Known as the phase characteristic function, then known as the first class (A class) linear phase characteristics; At the time, called the second class (B class) linear phase characteristics.
2, FIR filters with linear phase characteristics (length)
1) The time-domain characteristics
A Class: (1)
B: (2)
Group delay: a constant, so the A class and B class of linear phase characteristic referred to as constant group delay characteristics.
2) frequency-domain characteristics
A Class: N is odd (case 1): About three al symmetry.
N is even (case 2): on the odd symmetry ().
Class B: N is odd (case 3): About three odd symmetry.
N is even (case 4): On the odd symmetry, on the even symmetry.
3 points
(1) Case 1: You can achieve all filtering (low pass, high pass, band pass, band stop and point resistance, etc.).
(2) Case 2: impossible to have high-pass, band pass and point-stop filter.
(3) Scenario 3: You can only achieve band-pass filter.
(4) case 4: not achieve low-pass, band stop and point stop filter.
Second, the frequency sampling design method of design principles:
FIR digital filter is designed to meet the design requirements to find a filter or system unit impulse response function.
According to frequency of sampling theory, if the length, in the upper unit circle on the sampling interval be
(3)
As long as, there
, (4)
(5)
Thus, as long as that FIR digital filter frequency response function in the interval point sampling, we can determine the unit impulse response filter or system function, which is the frequency sampling design of the theory.
Frequency sampling frequency sampling is based on the above theory index constructed by the filtering characteristics of filter frequency response function approximation hope its in the sampled
, (6)
Then, obtain the unit impulse response, or obtain the system function. In this way, or is the result of FIR digital filter design.
Third, with the frequency sampling design of FIR filter design steps:
(1) According to the stop-band attenuation α minimum number of sampling points chosen transition zone m.
(2) to determine the width of transition zone B, estimate the frequency domain sampling points (filter length) N. If the increase in m were transitional zone samples, the transition zone width approximation into (m +1) 2π / N. When the N to determine when, m the greater the wider the transition zone. If the width of a given transition zone B, the requirement (m +1) 2π/NB, filter length N must satisfy the following estimation formula:
(3) to construct a wish to approximate the frequency response function:
=
Questions added: (4) According to (6) Type in the frequency domain sampling
(5) H (k) for N point IDFT, be the first class of linear phase FIR digital filter unit pulse response
6) test design results. If the minimum stopband attenuation does not meet the target, will have to change the value of transition zone sampling, up until the meet the requirements. If the filter does not meet the target frequency boundary requirement. If the filter does not meet the target frequency boundary requirements, will have to fine-tuning of the boundary frequency
4, frequency sampling design of FIR filters:
(1) The general frequency response function of the actual design of the ideal frequency response characteristics of the corresponding approximation as hoped, it will give the design simplified.
(2) linear phase FIR design constraints on and if, as the rate of sampling, said sampling phase
(3) the approximation error and the improvement measures, the estimated value
5, frequency sampling method and design characteristics of test results:
Features of this method are: the frequency domain directly involved in any frequency response of FIR digital filters, the concept clearly and directly. But difficult to control the border frequency. Therefore, the design, should be tested, can increase the frequency of sampling points to improve the accuracy of the boundary, but this will increase the cost of filters and calculation.
For narrow-band filter, even if the large passband and fewer non-zero sample, so that the interpolation of equation (5) items less effective, so that the slip road parallel to achieve low frequency sampling structure, so that filter cost rection, reced operations. Therefore, the design method for narrow-band filter design

辨析
answer for,answer to
⒈这两个短语都可表示“符合…需要”，其区别是：接needs,wishes,hopes,description等词时用answer to; 而接purpose时则只能用answer for。
⒉这两个短语都可表示“负责”，其区别是：answer for表示对事负责； 而answer to则表示对人负责。试比较：
I will answer for him.
他的事情由我负责。
I will answer to him.
我将对他负责。
answer sth,answer to sth
及物动词和“不及物动词+to”，这里有个语言史的问题，即有些动词过去带to而现在不带，而有些动词过去不带to而现在带，如listen; 还有些动词两者都能用，如approach。不过不带to的情况更普遍。answer的情况是用于“回答，答复”等直义时一般用作及物动词，即不带to。例如：
Answer my question,please.请回答我的问题。
用于“符合，适合”等转义时，两种用法均可，不过不带to时直接性较强。例如：
This dictionary answers (to) my needs.这本词典符合我的需要。
to answer,be an answer to
英语中系动词与动作动词相比，其语气往往显得较弱，所以下面两个句子，第一个显然更常用。
她脸上的表情就足以回答我的问题了。
Her facial expression alone answered my question.
Her facial expression alone was an answer to my question.
answer,reply,respond
这三个词意思相近，常可通用。例如：
I don't know what to answer〔reply,respond〕.我不知道该怎么回答。
它们之间的区别是：
⒈词源不同，answer来自古英语； reply来自古法语； respond来自拉丁语。
⒉answer和reply可指口头、书面或行动上的回答，而respond则偏重于用行动回答或响应。
⒊answer既可用作及物动词，也可用作不及物动词，还可用作名词； 而reply通常只用作不及物动词，但其后可接直接引语或that引导的宾语从句，用作及物动词时，宾语只能是所说的话； respond既可用作及物动词也可用作不及物动词，其名词形式是response。
⒋answer接letter,question等词时用作及物动词，即不加to，而reply和respond只能用作不及物动词，即必须加to。
⒌answer可接双直宾语，而reply和respond则不能。
⒍answer后可接人或物； reply的对象一般不能是人，而只能是物。
⒎answer多指对问题的回答； reply一般用于对某一陈述或主张的回答，特别是对相反意见、议论等的答复； 而respond通常指对号召、职责等作出响应或反应。
⒏answer后接a letter时只指复信表示收到来信； 而reply to a letter则指要答复来信中所提出的全部问题或提请注意的各点。
⒐作“给出答案”解时只能用answer，不能用reply和respond。
⒑表示“作出相应反应”，可用answer和respond，不能用reply。
⒒answer最普通，最常用； 而reply和respond都是正式用语，口语中少用。
正误辨析
一周前我给她回了信。
[误]I answered her letter for a week.
[正]I answered her letter a week ago.
[正]It is a week since I answered her letter.
[析]answer是瞬间动词，不表示持续动作，不可与表示一段时间的状语连用。 双解释义
C1. 回答； 回音 words spoken or written in return
C2. 答案 solution to a problem
U3. 反应 gesture or act done in return
基本要点
⒈answer用作可数名词时主要表示用口头或书面作出的“回答，答复，答辩”或表示最初不知道而经过思考之后才得出的“答案，解答”。
⒉answer前一般须有冠词、数词或其他能修饰可数名词的限定词（语），其后可接表示“针对…的”介词短语to sth (to不可换成表示所有关系的of或表示目的的for等介词）。
⒊know all the answers意为“（自以为）精通一切”。

词语辨析
answer,reply
这两个词的共同意思是“回答，答复”，都可用作名词或动词。其区别在于：
⒈answer主要指用语言文字回答问题、指责或争论，也可能是以行动满足要求或应付情况； reply则主要指用语言文字给予回答，进行解释等，也可指用行动回答。
⒉answer作为名词时，其后常接介词to; reply作为名词时，其后往往接介词to或者for。例如：
The Western answer to this move was the use of plane to supply food.西方对这一建议的答复是用飞机提供食品。
They gave her a reply for her claim.他们对她的要求做了答复。
⒊answer是普通用语，用得比较广泛； reply则较为正式。
