  7. Abstract:
  8. Due to the growth of information volume and increment in the speed of processor units, it is critical to achieve higher speed in data transaction systems. This necessity could be recognized in all fields, from digital data transactions on a chip and among its building blocks to data transactions among electronic boards and computerized systems in huge control constructions.
    Methods of data transmission have been improved both in terms of speed and simplicity for different applications in today’s enormous consumer electronics market. One possible option is to use conventional wires as physical channel of transmission system.
    The most important drawback of the wires is their relative high loss, especially at high frequencies. The aim of this research is to resolve and analyze this problem. Some mathematical methods are presented to model and describe wire channels, especially, cheap ones. Then some simple and practical equations are presented. Afterwards a common type of equalizer, called continuous-time linear equalizer, has been addressed and its specifications are linked to basic channel parameters. At the end, a cheap and simple sample of this type of equalizer is designed based on the developed model. The accuracy and effectiveness of the developed methods are tested and evaluated.
