Analysis on singularity characteristics of flow pattern signals of wavelet transform in gas - liquid two - phase flow pipelines 气液两相流流型信号的分形特征分析
The thesis researchs the basic theory of digital hdtv test pattern signal generating system and its realization based on soc ( system on chip ) 论文研究了数字高清晰度电视测试图案信号发生系统基本原理及其基于片上系统( soc , systemonchip )的具体实现。
Viewable test pattern signal provides an intuitionistic and convenient evaluating method , therefore , hdtv test pattern signal generating system become a hot research of world today 可视化的测试图案信号提供了直观、快捷的评测方法,因此,高清晰度电视测试图案信号发生系统成为当今世界的热门研究课题。
The thesis firstly summarizes the current research of hdtv test pattern signal , and introduces the hdtv technology , hdtv signal design reference standards , such as smpte international standards and chinese standards for hdtv digital video signal interface of studio 论文首先对hdtv测试信号研究现状进行了概述,并介绍了hdtv技术、 smpte国际标准及国内的演播室高清晰度电视数字视频信号接口等hdtv信号设计参考标准。
