'''TIMS''', or '''Telecommunication Instructional Modeling System''', is an [[Electronics|electronic device]] developed by Emona that is used as a [[Telecommunication|telecommunications]] trainer in educational settings and universities.<ref>{{Cite journal|last=Sarfaraz|first=Maysam|date=2011-05-01|title=EDUCATIONAL APPLICATIONS OF PARTIAL RECONFIGURATION OF FPGAS|url=https://scholar.utc.edu/cgi/viewcontent.cgi?article=1052&context=theses|journal=Thesis from University of Tennessee at Chattanooga}}</ref><ref name=":5">{{Cite book|last=Silva|first=Mário Marques da|url=https://books.google.com/books?id=A6x-DwAAQBAJ&newbks=0&printsec=frontcover&pg=PT23&dqq=emona+tims&hlpg=enPT23|title=Cable and Wireless Networks: Theory and Practice|date=2018-09-03|publisher=CRC Press|isbn=978-1-4987-5154-4|language=en}}</ref><ref>{{Cite book|last=Conference|first=American Society for Engineering Education|url=https://books.google.com/books?id=vmRGAAAAYAAJ&newbks=0&printsec=frontcover&dq=emona+tims&q=emona+tims&hl=en|title=ASEE Annual Conference Proceedings|date=2004|publisher=American Society for Engineering Education|language=en}}</ref>

== History ==

TIMS was designed at the [[University of New South Wales]] by Tim Hooper in 1971. It was developed to run student experiments for electrical engineering communications courses.<ref name=":0">{{Cite journal|last=Manfredini|first=Carlo|date=1987-06-01|title=TIMS: Prize-Winning Learning System for Communications|url=https://worldradiohistory.com/hd2/IDX-AUSTRALIA/IDX/Archive-Electronics-Australia-IDX/IDX/80s/EA-1988-01-OCR-Page-0096.pdf|journal=Electronics Australia|pages=96}}</ref> Hooper’s concept was developed into the current TIMS model in the late 1980s.<ref name=":3">{{Cite journal|last=Breznik|first=Alfred|date=2004-01-30|title=Hands-on learning system for Wireless laboratory courses|url=https://peer.asee.org/hands-on-learning-system-for-wireless-laboratory-courses.pdf|journal=Proceedings of the 2004 American Society for Engineering Education Annual Conference & Exposition|pages=9.658.1-91–9.658.5}}</ref> In 1986, the TIMS project won a competition organized by [[Electronics Australia]] for development work using the [[Texas Instruments TMS320]].<ref name=":0" /> Emona Instruments also received an award for TIMS at the fifth Secrets of Australian ICT Innovation Competition.<ref>{{Cite web|title=Sticisce avstralskih Slovencev - Slovenian network in Australia|url=http://www.glasslovenije.com.au/aktualno/emonaAward2007.htm|access-date=2021-07-08|website=www.glasslovenije.com.au}}</ref>

== Methodology ==

TIMS uses a block diagram-based interface for experiments in the classroom. TIMS can model mathematical equations to simulate electric signals, or it can use block diagrams to simulate telecommunications systems.<ref name=":1">{{Cite journal|last=Breznik|first=Alfred|date=2004-10-01|title=TIMS-301 USER MANUAL|url=http://ecelabs.njit.edu/ece489/misc/tims301_user_manual.pdf|journal=EMONAEmona INSTRUMENTSInstruments PTYPty LTDLtd}}</ref><ref name=":3" /> It uses a different hardware card to represent functions for each block of the diagram.<ref>{{Cite journal|last=Purani|first=Abhilash M.|date=2010-04-23|title=AN EVALUATION OF LOW COST FPGA-BASED SOFTWARE DEFINED RADIOS FOR EDUCATION AND RESEARCH|url=https://scholar.utc.edu/cgi/viewcontent.cgi?article=1509&context=theses|journal=A Thesis Presented for the Master of Science Degree Thethe University of Tennessee at Chattanooga}}</ref>

TIMS consists of a server, a chassis, and boards that can emulate the configurations of a telecommunications system.<ref>{{Cite journal|last=Sandoval|first=Jose R Santamaria|date=2020-04-01|title=Application of the EMONA TIMS platform for the Telecomunications Engineering career at UNED Costa Rica|url=https://www.researchgate.net/publication/349042618_Application_of_the_EMONA_TIMS_platform_for_the_Telecomunications_Engineering_career_at_UNED_Costa_Rica349042618|journal=Engineering Education}}</ref> TIMS uses electronic circuits as modules to simulate the components of [[Analog communication|analog]] and [[Digital Communications System|digital communications systems]].<ref name=":2">{{Cite journal|last=Khan|first=Muhammad Ajmal|date=2018-06-01|title=Enhancing Students’Students' Lab Experiences using Simulink-based Pre-Labsof Corresponding Hardware-based Labs|url=http://people.cst.cmich.edu/yelam1k/asee/proceedings/2018/1/69.pdf|journal=Proceedings of the 2018 ASEE North Central Section Conference}}</ref><ref>{{Cite journal|last=Sakovičs|first=Ričards|date=2019|title=Digital-to-analog and Analog-to-digital Converter Operational Research|url=https://nda.rtu.lv/en/view/24448|journal=Riga Technical University Graduate Papers}}</ref> TIMS modules can perform different functions such as signal generation, [[signal processing]], signal measurement, and [[digital signal processing]].<ref name=":2" /><ref name=":1" />
