Design of signal switching in automatic test system 的电源自动测试系统的设计
Several progresses are made in the development of software and hardware in the video signal switch module 对视频混合电路模块的软硬件开发调试也取得了一定的进展。
Isolated contacts and low operating power make reed relays an ideal choice for many signal switching applications 干簧式继电器的隔离触点和低工作电流使其成为了多种信号切换应用中的理想选择。
Based on the analysis of the defect , a new control method is proposed to address the abrupt volume change on tv signal switch 摘要针对电视接收机信号切换时音量常常突兀变化的设计缺陷,在对其进行综合分析的基础上,提出一种新的控制方式。
The large physical size and limited isolation ( due to materials requirements and construction ) make this type of relay a poor choice for signal switching 较大的物理尺寸和受限的隔离(由于材料和构造的要求)使这类继电器不适合于信号切换。
After finishing multimedia player function , i bring forward the scheme in control of video signal switch through gpio pins in ep9315 基本实现了多媒体模块的视频播放功能,在此基础上提出了通过ep9315上的gpio口控制混合电路模块的视频信号切换功能方案。
A signal switch may also send a query message to the signal control point , which acts as a centralized database for routing instructions , such as how to handle 800 / 888 calls 信号交换机也可以向信号控制点发送一个查询信息,该信号控制点起到路由指令(如怎样处理800 / 888对方付费电话)的集中化的数据库的作用。
Automatic vehicle system are made up of several moduls , those moduls are vector electronical map module , position module , communication module , multimedia player module and video signal switch module . in this system , we can realize the position and navigation of vehicle in graphics mode , and demand geographical information , make use of wireless communication , enjoy the multimedia player and so on 该系统由矢量电子地图模块、定位模块、通信模块、多媒体视频播放模块及视频混合电路模块这几个模块有机组成,用于实现车辆图形化定位导航、信息查询、无线通信、多媒体播放等多种功能。
And the solutions of the three problems above are discussed : the solution to the simulcast interfering which is caused by the simulcast delay spread ( sds ) and the zero - beating is given in chapter four . based on the well understanding of the principle of ms - i / h / 0 in ipnp , the examples are given in chapter five on how to solve the problem of communication interruption between paging zones . through the analyse of signal switching between chengdu and deyang , the synchronization error between flex frames , and the bug in the multi - frequency roaming principle are pointed out 通过以上分析,文章探讨了对上述三个问题的解决: ?对同播干扰问题,分别分析了时延差和零拍频所造成同播干扰的客观存在,探讨了系统设计和网络优化的基本方法; ?对ipnp联网障碍,提出了在掌握ipnp对各pncc作为输入局归属局?输出局( ms ? i h o )的灵活定义、以及相关参数配置原理的基础上,分析联网障碍的思路; ?对信号切换障碍,以成都和德阳两地的局部广域覆盖为例,分析了flex帧失步和flex多频漫游原理设计缺陷的客观存在,并探讨了相关的解决方法和建议。
