  • Millimeter+Wave+Communication+Systems

    This book presents millimeter wave communication system design and analysis at the level to produce an understanding of the interaction between a wireless system and its front end so that the overall performance can be predicted. Gigabit wireless commu- nications require a considerable amount of bandwidth, which can be supported by millimeter waves. Millimeter wave technology has come of age, and at the time of writing the standards of IEEE 802.15.3c, WiGig, Wireless HD TM , and the European Computer Manufacturers association have recently been finalized.

  • Digital+Control+Applications

    My association with the theory of controls in continuous time started during my studies at the Indian Institute of Technology, Kharagpur, India, in 1974 as an undergraduate student in the Controls and Power program. The initial introduction by Professors Kesavamurthy, Y. P. Singh, and Rajagopalan laid the foundation for a good basic understanding of the subject matter. This pursuit and further advanced study in the field of digital controls continued during my days as a graduate student in the Electrical and Systems Engineering Department at the University of Connecticut in Storrs, from 1983 to 1988.

  • DeviceNet协议

    一、DeviceNet概述DeviceNet 规范由Rockwell 自动化公司开发,并将其作为一个基于 CAN协议的开放式现场总线标准而公布。最初的 DeviceNet产品在1995年初出现。DeviceNet协议特别为工厂自动控制而定制,它在美国和亚洲扮演了非常重要的角色。在欧洲,越来越多的系统方案使用 DeviceNet来实现。ODVA(Open DeviceNet Vendor association)是所有DeviceNet产品开发者的组织,它成立于 1995年,并获得了Rockwell 自动化公司所有知识产权的转让。该组织按照公司的原则进行运作,并确保所有成员都有同等的发言权。它负责DeviceNet标准的制定和更新。此外,ODVA还致力于DeviceNet在全球的推广和市场化。开发基于DeviceNet的产品必须遵循 DeviceNet规范。DeviceNet规范分Volume 1,Volume Il两部分。用户可以从ODVA协会寻找关于 DeviceNet开发源代码的信息:基于 CAN-bus的硬件则可以从 PHILPS.Intel等半导体供货商那里获得
