不足之处

Fast Fourior Transform plays an important roll in digital signal processing,its the kernel algorithm in a lot of process for signal processing.this paper first summarizes many algorithm for Fast Fourior Transform that in common use and synthesizes many reasons to adopt the radix-2 Demation-in-Frequency algorithm,then it compares two ways of implementing digital signal processing,the two ways are in field-programmable gata array and in programmable digital signal processor respectively.it points out the advantage and disadvantage of two ways.

快速傅立叶变换是数字信号处理中的重要内容之一，是很多信号处理过程中的核心算法。本文先总结了快速傅立叶变换的一些常用算法，并综合种种因素，采用了基2按频率抽取算法作为实现算法，然后将以现场可编程门阵列和以DSP处理器这两种实现数字信号处理的方式进行了比较，指出了各自的优点和不足之处。

In this paper we use the expert-investigation method to distinguish the risks of the project and then we build a model and to use the analysis of hieratical processto evaluate the risks of the project. After this we get the weighs of every risk we distinguish and we also get the high, middle and low probability of the projects whole risk. And then we analyze the two important risks of the project, the market risk and the design risk, we also make out the methods to control the risks.

本文在对周公山楠水阁酒店工程的风险管理研究中，采用了专家调查法对咳项目所面临的风险进行识别，并建立了风险评估模型，在此基础上用层次分析法对各风险因素进行评估得出了各种风险因素所占的权重和整体工程项目的风险度大小，着重对市场风险和设计风险做了详细分析，在分析的基础上给出了相应的风险控制措施和方法，最后总结了在风险管理过程中的成绩及不足之处。
