Modern, large scale, display systems are migrating from traditional technologies such as incandescent, fluorescent and mechanical to sophisticated products based on LEDs. LED displays offer power savings and a superior visual experience in a range of products from programmable signage to large-scale video displays and commercial installations.

Introduction Matlab is an ideal tool for simulating digital communications systems, thanks to its easy scripting language and excellent data visualization capabilities. One of the most frequent simulation tasks in the field of digital communications is bit-error- rate testing of modems. The bit-error-rate performance of a receiver is a figure of merit that allows different designs to be compared in a fair manner. Performing bit-error-rate testing withMatlab is very simple, but does require some prerequisite knowledge.

Need to make sense of the many changes to Visual Basic for the new .NET platform? VB .NET Language in a Nutshell introduces the important aspects of the language and explains the .NET framework. An alphabetical reference covers the functions, statements, directives, objects, and object members that make up the VB .NET language. To ease the transition, each language element includes a "VB .NET/VB 6 Differences" section.

Servomotors are available as AC or DC motors. Early servomotors were generally DC motors because the only type of control for large currents was through SCRs for many years. As transistors became capable of controlling larger currents and switching the large currents at higher frequencies, the AC servomotor became used more often. Early servomotors were specifically designed for servo amplifiers. Today a class of motors is designed for applica-tions that may use a servo amplifier or a variable-frequency controller, which means that a motor may be used in a servo system in one application, and used in a variable-frequency drive in another application. Some companies also call any closed-loop system that does not use a stepper motor a servo system, so it is possible for a simple AC induction motor that is connected to a velocity controller to be called a servomotor.

This example program is the source code for the FT232BM Test Application from our Utilities page. It can be used to test the handshaking lines on FT232BM based RS232/RS485/RS422 designs. This program can also be used for programming the external EEPROM over USB in a manufacturing environment. The test features require the test cable shown on ST_232_245.pdf to be connected. Our D2XX direct drivers should be installed for this application. The code can be modified to fit your requirements. To download the application source code , click here. To download the test cable specification, click here.

QuickSteps books are recipe books for computer users. They answer the question 揌ow do I...??by providing a quick set of steps to accomplish the most common tasks with a particular program. The sets of steps are the central focus of the book. Sidebar QuickSteps provide information on how to do quickly many small functions or tasks that are in support of the primary functions. Sidebar QuickFacts supply information that you need to know about a subject. Notes, Tips, and Cautions augment the steps, but they are presented in a separate column to not interrupt the fl ow. Brief introductions are present, but there is minimal narrative otherwise. Many illustrations and fi gures, a number with callouts, are also included where they support the steps.
