DESIGNing for Networked Communications: Strategies and Development is a book about how we plan, use, and understand the products, dynamic social processes, and tasks upon which depend some of the most vital innovations in the knowledge society—social as well as technological ones. Focusing on various forms of design, implementation, and integration of computer-mediated communication (CMC), the book bridges the academic fields of computer science and communication stud- ies.

Methods for DESIGNing a maintenance simulation training system for certain kind of radio are introduced. Fault modeling method is used to establish the fault database. The system sets up some typical failures， follow the prompts trainers can locate the fault source and confirm the type to accomplish corresponding fault maintenance training. A training evaluation means is given to examining and evaluating the training performance. The system intuitively and vividly shows the fault maintenance process， it can not only be used in teaching， but also in daily maintenance training to efficiently improve the maintenance operation level. Graphical programming language LabVIEW is used to develop the system platform.

Abstract: Most magnetic read head data sheets do not fully specify the frequency-dependent components andare often vague when specifying other key parameters. In some cases, the specifications of two very similarheads from two different manufacturers might be quite different in terms of parameters specified and omitted.The limitations in the data sheets make DESIGNing an optimum card reading system unnecessarily difficult andtime consuming. This document outlines a strategy to overcome the above shortcomings and offers guidelinesto overcome the noise issues.

Abstract: What can be simpler than DESIGNing with CMOS and BiCMOS? These technologies are very easy to use butthey still require careful design. This tutorial discusses the odd case of circuits that seem to work but exhibit somepeculiar behaviors—including burning the designer's fingers!

Precision 16-bit analog outputs with softwareconfigurableoutput ranges are often needed in industrialprocess control equipment, analytical and scientificinstruments and automatic test equipment. In the past,DESIGNing a universal output module was a daunting taskand the cost and PCB real estate associated with thisfunction were problematic, if not prohibitive.

This unique guide to DESIGNing digital VLSI circuits takes a top-down approach, reflecting the natureof the design process in industry. Starting with architecture design, the book explains the why andhow of digital design, using the physics that designers need to know, and no more.Covering system and component aspects, design verification, VHDL modelling, clocking, signalintegrity, layout, electricaloverstress, field-programmable logic, economic issues, and more, thescope of the book is singularly comprehensive.

Finite state machines are widely used in digital circuit designs. Generally, when DESIGNing a state machine using an HDL, the synthesis tools will optimize away all states that cannot be reached and generate a highly optimized circuit. Sometimes, however, the optimization is not acceptable. For example, if the circuit powers up in an invalid state, or the circuit is in an extreme working environment and a glitch sends it into an undesired state, the circuit may never get back to its normal operating condition.
