Computer Hardware Diagnostic Software

It has been predicted that the arrival of the all-digital telephone network would soon make modems obsolete. Yet this has not happened, nor is it likely to for at least another ten years. Meanwhile, the ever-increasing demand for data-communications systems, of which analog-based modems are a large and essential part, continues to elicit new theories and exciting applications. This book examines these new theories and applications of modem design, and includes several practical examples of how to choose and design all the major components of a modem. Emphasizing an applied approach throughout, The Theory and Practice of Modem Design first describes the various media through which data must be transmitted— especially the most important one, the telephone network. Then, after a review of the basic theories of data transmission, the book discusses modulation methods, including the analysis of two new, controversial methods, with a fresh assessment of their usefulness and a description of how they can be implemented. Next, the book describes the overall architecture and all the major components of a receiver (with separate chapters for the critical functions of timing and carrier recovery, and linear and nonlinear adaptive equalization) using a careful blending of theory and specific practical examples, and considering both hardware and software implementations. The Theory and Practice of Modem Design also discusses two topics of great current interest to modem designers: convolutional coding for error correction and full-duplex operation (using both frequency division multiplexing and adaptive echo cancellation). There is also a section that explains all the ancillary functions that apractical modem must perform, plus two appendices that describe computer programs and diagnostic tests that can be used for designing and debugging.

Computer hardware - Computer hardware is the physical parts of a computer, as distinguished from the computer software or computer programs and data that operate within the hardware. The hardware of a computer is infrequently changed, in comparison with software and data which are "soft" in the sense that they are readily created, modified or erased on the computer.

Computer software - Computer software (or simply software) is that part of a computer system that consists of encoded information (or computer instructions), as opposed to the physical computer equipment (hardware) which is used to store and process this information. The term is roughly synonymous with computer program but is more generic in scope.

Hardware/software codesign - The boundary between hardware and software is increasingly blurred in computer-based systems. When designing systems where both aspects are important and the interface is a critical part of the overall design, hardware/software codesign is an important approach to ensure an efficient final implementation.

Hardware architecture - Hardware is an expression used within the engineering disciplines to explicitly distinguish the (electronic computer) hardware from the software which runs in it. But hardware, within the automation and software engineering disciplines, need not simply be a computer of some sort.
