LCD projection televisions, such as this “Television of the Future” could replace the CRT-based television if certain performance criteria are obtained One criteria being addressed is the need for a very bright, optically efficient point source for projecting an image through a small LCD If new lighting technologies are developed, such as an illumination source that can provide a brighter image with better colors than current CRT technology, then the consumer television market will certainly change (Photo courtesy of Thomson Multimedia.)

LECTRONIC DESIGNERS have placed increasing significance on digital devices since the late 1960s This is due primarily to the greater reliability and improved accuracy gained when using electronic devices in a two-level mode (binary mode) as compared to using electronic devices in a continuous mode (analog mode) As silicon integrated circuits (ICs) became denser and more consistently reproducible over the past few decades, so did digital electronic devices Today digital circuits and digital systems produced from digital devices can be found in every walk of life ranging from children’s toys, kitchen appliances, laboratory instruments, personal and workstation computers to space shuttle and satellite applications

The intent of this section is to present topics related to the utilization and application of digital devices Chapter 79 establishes the foundation for digital logic elements beginning with IC, logic gates, logical families, bistable devices, and optical devices Discussed in the next chapter are memory devices, which include integrated circuits (RAM, ROM), disk systems, magnetic tape, and optical disks Chapter 81 on logical devices discusses switching algebra, logic circuits, registers, programmable arrays (PAL, FPGA), and arithmetic logic units The next chapter explains the microprocessor, perhaps the best-known digital device The topics covered include practical microprocessors and microprocessor applications Chapter 83 on displays consists of the light-emitting diode, the liquid-crystal display, the cathode ray tube, and the plasma display The gathering of digital E

information, referred to as data acquisition, is discussed next No digital system is released to production without extensive testing Chapter 85 presents methods of testing and design for testing

The variety of topics presented in this section should provide readers with a contemporary overview of digital devices and their applications To obtain additional information, the reader may refer to the References and Further Information in each chapter
