The book represents a course reference for Universities and Engineering Schools offering courses on applied computer-controlled systems and system identification. In addition to its academic audience, Digital Control Systems is aimed at practising engineers wishing to acquire the concepts and techniques of system identification, control design and implementation using a digital computer. The industrial references for the techniques presented in the book and the various applications described provide useful information for those directly involved in the real-world uses of control. Readers who are already familiar with the basics of computer-controlled systems will find in this book a clear, application oriented, methodology for system identification and the design of various types of controllers for single-input, singleoutput (SISO) systems.

CC字幕标准, 从传输到应用描述了CC字幕的方方面面，其中CC字幕的包结构CDP对于一般编程人员很有用

This book tries to address different aspects and issues related to video and multimedia distribution over the heterogeneous environment considering broadband satellite networks and general wireless systems where wireless communications and conditions can pose serious problems to the efficient and reliable delivery of content.Specific chapters of the book relate to different research topics covering the architectural aspects of the most famous DVB standard (DVB-T, DVB-S/S2, DVB-H etc.), the protocol aspects and the transmission techniques making use of MIMO, hierarchical modulation and lossy compression. In addition, research issues related to the application layer and to the content semantic, organization and research on the web have also been addressed in order to give a complete view of the problems. The network technologies used in the book are mainly broadband wireless and satellite networks. The book can be read by intermediate students, researchers, engineers or people with some knowledge or specialization in network topics.,解压密码 share.weimo.info
