UNITED ELECTROTECHNOLOGIES
ADVANCED DIGITAL TRANSMISSION SYSTEMS LABORATORY (UE-ADTS)
In most countries today, Telecommunication services are evolving rapidly from a collection of separate and largely diverse systems (telephone, telex, public and private data networks and so on) towards a universal network, in which a wide variety of services are integrated using a common (digital) form of transmission.
Digital Communication Systems by virtue of their versatile features have been able to establish a solid regime in the field of Communication promising a no looking back scheme in the present scenario. With the advances in Technology, the world is shrinking globally in terms of Communication and Information sharing (thanks to the growth of Networking). However the good buildings are built only on firm foundations, the fundamentals are to be respected, appreciated and digested.
United Electrotechnologies DESK systems shall be used in Laboratories for
· Demonstrate and Teach
· Experiment and Learn
· Development of SKills and Application
United Electrotechnologies, with its expertise in the field of Communication and Networking, adds Advanced Digital Transmission Systems Laboratory to the series of UE-DESK Products. The UE-ADTS modules provides a platform
Building Blocks of Digital Communication Technologies
The functional block diagram shown above illustrates the signal flow through a typical DCS (Digital Communication System). The UE-DESK systems provides a platform for Teaching and Learning of each one of the system separately and these modules shall be integrated to form the typical DCS
UE-Advanced Digital Transmission Systems Laboratory setup:
· Target platform – UE-ADTS:
o Plug in – Plug out modules for various experiments for different blocks in typical Digital Communication system (DCS)
o The set of experiments provided with UE_ADTS provides a platform to learn the DCS as individual blocks or integrated.
o The user designed modules shall be interfaced with the other standard blocks of UE-ADTS
