P. F. Van Haperen,B. Gremmen,J. Jacobsthe match between the signal and channel transmission characteristics. This could be done by modulating it onto an analog waveform of known bandwidth or by coding the digital signal in some way. If data is transmitted over a channel without modulation the term . is used to describe the communications.

Critical Thresholds in Fear and Panicich will make the connecting together of computers, and other sources of information much more straightforward. This chapter discusses some advances which are already well into their development life cycle and which will have an impact on data communications over the next few years.

Introduction,subject. Most of the topics mentioned are explained in much more detail in the following chapters. The concept of layered communications is explained, so that it can be used as a framework for the rest of the book. However, before looking at data communications specifically, the idea of communication in general is examined.

Baseband Digital Transmission,the match between the signal and channel transmission characteristics. This could be done by modulating it onto an analog waveform of known bandwidth or by coding the digital signal in some way. If data is transmitted over a channel without modulation the term . is used to describe the communications.
