5 noise restraining hardware system : the system ' s core is tms320c5402 chip , including a / d 、 d / a 、 rom and logical circuit , it has realized noise restraining . there are five parts in this paper 5语音降噪的硬件系统:以tms320c5402芯片为核心、包括模数、数模转换电路,外存储器和逻辑控制电路在内的硬件电路,实现了语音降噪。
At the same time , the parameter monitoring circuit is designed to check the operational parameters of pharos that include voltage of power supply , operational current , based on lm339 voltage comparer , optical sensor and logical circuit 以lm339电压比较器为核心,结合光传感器、逻辑电路等,设计出参数检测电路,监测航标灯的电源电压、工作电流等工作参数。
The author has selected the composing coms chips of the related module , communication protocol and designed logical circuits , etc . and lastly , the hardware structure of ienps is turned out , as well as its monitoring software flow 选择了相关模块的组成芯片、通讯协议并且设计了相关模块的逻辑电路等;最后,实现了实时电子巡更系统硬件系统,给出了控制软件流程。
To build new scps , used to load vpmn service logic so as to build a network of logical circuits on the basis of the plmn , providing the users with functions of dedicated numbering and abbreviated number dialing and taking charge of billing 新建scp ,用于加载vpmn业务逻辑,以便在公用移动网基础上建立一个逻辑话路网,给用户提供专用编号计划、缩位拨号等业务功能并负责计费工作。
Also we introduced the max + plus ii , the digital logical circuit circumstance , and how the design the digital logical circuit on this circumstance . we also wrote a program to show the signal , the number of strain and the strain direction and so on 对cpld的数字逻辑开发环境max + plusii做了简明扼要的介绍,并在此开发环境上做了判向电路的数字逻辑设计,最终将测试结果显示在液晶显示屏上。
