The telecommunication laboratory provides the students with a hands-on experience on several aspects of analog and digital communications. In addition to hosting applied research opportunities for graduate students, the laboratory also serves the undergraduate- and graduate-level courses: EE 479 Telecommunications Laboratory and EE 562 Microwaves. The screened room (Faraday's Cage) located within the laboratory blocks out external electric fields and allows the researchers to accurately design and test communications transmitters and receivers. Current research conducted in this section of the lab includes the design of robust ultra-wideband (UWB) communications transceivers. The telecommunications experiment sets along with the basic measuring instruments and spectrum analyzers serve the EE 479 Telecommunications Laboratory course. The students conduct hardware experiments on several aspects of telecommunications covering a broad spectrum starting from basic analog-to-digital conversion to advanced digital modulation schemes. Additionally, several personal computers with LabView software installed are provided in the lab to allow students design and verify software experiments. The microwave experiment sets, microwave signal generators, and associated measuring instruments allow the students of the graduate-level course EE 562 Microwaves to design and experiment with several aspects of microwave transmission lines.

It is equipped properly according to a schedule that extends from acquiring knowledge and skills about practical working principles of passive and active components and developing the ability to use measuring instruments and techniques effectively, towards learning selected integrated circuits and basic electronic circuit building blocks and having the opportunity to experience specialized electronic circuits designed for particular jobs. All the equipment has been renewed and the students are provided with the means to work both with conventional analog devices and with more contemporary digital instruments. Particularly for the students who select the electronics option in the fourth year, this is a laboratory that gives opportunity to work individually, with the desired equipment, and without time constraint; thereby providing a free environment in the direction of the will and interest of the student. Besides the laboratory courses mentioned above, it merrily hosts the circuit design and implementation experiments performed as part of term homeworks (e.g. in EE 437 and EE 438), graduation projects (EE 491, EE 492) and graduate studies. In a separate room within the laboratory, tools such as PCB cutter, mechanic drill, etc. are also available, which provides the necessary means for those who want to produce his/her own PCB board and finalize his/her design including boxing. Its door is open any time within working hours to every student who wants to experiment more. In order to prepare our students for the professional life, whether academic or industrial, we cooperate with them by providing a positive communication.

A design project can also be assigned using available using the available experimental set-up.The first set of experiments deal with the input transducers and actuators such as slotted opto transducer, strain gauge, I.C. based temperature transducers which are the essential building blocks of the control of a number of physical systems. The second set of experiments is an extension of the first set and deals with output transducers such as a DC solenoid, a permanent magnet DC motor.In the third and fourth sets, a permanent magnet DC motor is used to introduce servo feedback control. First an analog experimental set up is used and the general characteristics of the DC motor are studied. The influence of the feedback gain and velocity feedback is shown on the position control of the DC motor. Then a digital control set up which includes an interface (with A/D and D/A converters) with a PC is used. First, position control and speed control experiments are repeated with control algorithms driven by the PC and position and velocity measurements supplied by a digital encoder. Following these experiments, the Proportional, Derivative and Integral (PID) control concepts are introduced and tested for position control using the digital control set up.
