在人们的生产活动和社会活动中常常会遇到这样的问题:经过一段时间之后,需要对具有相同类型的部门或单位(称为决策单元)进行评价,其评价的依据是决策单元的“输入”数据和“输出”数据,输入数据是指决策单元在某种活动中需要消耗的某些量,例如投入的资金总额,投入的总劳动力数,占地面积等等;输出数据是决策单元经过一定的输入之后,产生的表明该活动成效的某些信息量,例如不同类型的产品数量,产品的质量,经济效益等等.再具体些说,譬如在评价某城市的高等学校时,输入可以是学校的全年的资金,教职员工的总人数,教学用房的总面积,各类职称的教师人数等等;输出可以是培养博士研究生的人数,硕士研究生的人数,大学生的人数,学生的质量(德,智,体),教师的教学工作量,学校的科研成果(数量与质量)等等.根据输入数据和输出数据来评价决策单元的优劣,即所谓评价部门(或单位)间的相对有效性.(In people s productive activities and social activities often encounter such a problem: After a period of time, need to have the same type of departments or units (referred to as the decision-making unit) to evaluate the basis for his assessment in decision-making unit "input "Data and" output "data, input data refers to the decision-making unit in certain activities that need to consume certain amount of, for example, the total funds invested, the investment of the total workforce number, area, etc. output data through the decision-making unit After a certain input to produce the show the effectiveness of the activity of certain amount of information, such as different types of product quantity, product quality, economic efficiency and so on. Be more specific, said, for example, in evaluating a city s institutions of higher learning, the input can be the year the school funds, the total number of faculty, teaching a total area of space, all kinds of titles the number of teachers, etc)

cic
在信号处理中,信号发射时,信号通过载波,调制,以电磁波的形式发射出来
在接收端,射频信号通过天线接收,超外差式等方式进行处理,变频到中频
然后通过数字技术对中频信号进行处理,此时的中频信号采样率很高,多达几十兆赫
而要解调出来的信号很小,此时就要经过滤波来得到我们需要的信号
如果直接设计滤波器,阶数会非常庞大,软件,硬件设备都承受不了
因此,一般常用的技术是进行下变频处理,其主要技术就是通过抽取滤波进行下变频
常用的滤波器就是CIC抽取, 希望可以帮助一些坛友解决基本的问题。
(In signal processing, signal emission, signal through the carrier, in the form of electromagnetic wave modulation, launched
In the receiver, rf signals through the antenna, specialized superheterodyne type means such as processing, the frequency conversion to intermediate frequency
Then through digital technology of intermediate frequency signal processing, at this time of intermediate frequency signal sampling rate is very high, as many as several decades MHZ
But the signal demodulation out is very small, at this time would be passing filter to get what we need signal
If design directly filter, order number be colossal, software, hardware equipment all suffer
Therefore, the technology is usually used for down-transducer processing, its main technical is by extracting filtering down-transducer
Commonly used filter is CIC extraction, the hope can help some friends solve basic problems of the altar.)
