Title: COMMUNICATIONS LABORATORY
Demonstration of fundamental signal processing techniques and communication algorithms using software packages. Various analog and digital modulation schemes.
Prerequisites by Topic:
Signal and Systems
Fundamentals of Communication Systems
Coordinator: Mutlu Koca, Professor and Electrical Engineering
Goals: Showing the analog/digital modulation and signal processing techniques, through the experiments by using LabView software and certain hardware experiment kits to seniors majoring in communications.
At the end of this course, students will be able to:
· Design communication circuit experiments by using LabView software.
· Understand the effects of changing some parameters of an analog or digital communication circuit or system.
· Understand the difference between the real life problems in communication circuits and theoretical studies.Conduct a communication experiment using hardware and software.
· Write a formal experiment report.

This course is a 1-credit Lab. course. Most of the experiments will be performed by using Lab-View software tools, which is available on the PC’s in the Lab. Students, may get their copy of the software to study at home. Students are supposed to design the experimental set-ups by using the standard “virtual instrument”s of the software and given modules. In addition to the soft experiments some of the experiments will be performed on the real hardware.
Each student will prepare a Lab. Report for each topic. The student will present his/her solution to the problem, printouts of the numeric results, waveforms, diagrams etc. in the report. The reports should be submitted the next period of Lab.
The grading = 40% Final + 30%Midterm & Term Project + 30% Lab performance&Reports (subject to minor changes)
Computer Resources:PC’s (with LabView software installed) in the Communications Lab.
Laboratory Resources:AM/FM, PCM/TDM experiment kits and standard measuring instruments in the Telecommunications Lab.
a) An ability to apply knowledge of mathematics, science and engineering. Students should use the basic signals, systems and telecommunication theory to interpret the outcomes of the experiments.
b) An ability to design and conduct experiments, as well as to analyze and interpret data. During the lab. sections, students learn how to implement a given circuit by using LabView virtual instruments, how to measure the different quantities and how to interpret the outcomes. Each student should perform 10 experiments and prepare reports. The interpretation of the results should be given in the reports.
c) An ability to design a system, component, or process to meet desired needs. Each student will design a soft experiment, as a term project. The instructor will give the specifications of the circuit or system to be designed.
g) An ability to communicate effectively. Each student should prepare lab. reports and presents his/her term project experiment. So, students learn how to prepare official reports how to demonstrate an experiment.
k) An ability to use the techniques, skills and modern engineering tools necessary for engineering practice. The students learn the structure and usage of one of the most common modern graphical software: LabView. They also use modern laboratory equipment, during hardware experiments (such as spectrum analyzers and oscilloscopes) and use computers for report writing.
