Modern science and engineering relies heavily on understanding computer hardware and software in order to make effective use of these tools in the laboratory and industrial environments. The authors have succeeded in producing a highly readable source that will serve both newcomers to the field as well as experienced professionals. People who use computers for data acquisition, and hardware or software development for laboratory and process control will find a wealth of information. The book includes both fundamentals and applications. The role of the computer in instrument systems is described in the first part of the book as well as a number of practical examples. The second part of this text explores specific software packages and their capabilities for such applications as: Instrument design and simulation; data acquisition; data processing; and finally the potential of artificial intelligence in instrument design. The full integration of theory with practical applications of leading software packages will make this an extremely useful reference for emerging computer based instrument technology.
