Course Structure: This is a Lab. oriented introductory electrical engineering course. The Lab. experiments will start on the second week of the semester. Each Lab. group will be composed of three students and will perform 9 experiments. Each student will prepare the reports of two selected experiments. The instructor will announce the Lab. groups and the experiment dates. The lectures are separated in two main sections. In the first section of the lectures the measurement principles and the physical properties of electronic components will be studied. The second section covers the conventional electronic design and electronic CAD/CAM. This section will be supported by a term project. Each student is expected to draft, design, and realize a working electronic circuit. Personal computers will be used intensively for electronic drafting, simulation and PCB design. Lab assistants will help students for their projects in the lab and mechanical workshop. However the students are expected to finish their projects in their spare times using either their own PC’s or departments PC lab. Students are supposed to buy the components of their project.There will be two midterms and one final exam. These exams will cover the lectures as well as the lab. experiments and the term project.

Grading:

1. Final (30%)
2. Midterms (30%)
3. Homeworks (8%)
4. Lab Performance and Reports (15%)
5. Term Project (17%)

Laboratory Resources: Measurement & Networks Lab., Mechanical Workshop, Dark Room.

Outcome Coverage:

• An ability to apply knowledge of mathematics, science and engineering. It is necessary to use the basic mathematics, analysis methods, physics and basic engineering concepts to be able to understand this course. Students are encouraged to review the previous courses. They learn statistical treatment of measurement data and engineering point of view of interpretation of the results.

• An ability to design and conduct experiments, as well as to analyze and interpret data. During the lab. sections, students learn how to set up a given circuit, how to measure the different electrical quantities and how to interpret the outcomes. All groups perform 10 experiments. However only two selected experiments are reported by each student. The interpretation of the results should be given in the reports.

• An ability to design a system, component, or process to meet desired needs. Although the electronic background of the class is not enough to design a new circuit they learn to implement a circuit with given specifications, they learn how to process the circuit to meet desired needs of the project. They test the finished product by measuring the electrical characteristics and do necessary modifications if necessary.

• An ability to function on multi-disciplinary teams. The lab. experiments are performed by groups of three students. They learn how to share roles during the experiments, such as assembler, reader of instruments and reporter.

• An ability to identify, formulate and solve engineering problems. With the homework and exams, students are forced to find solutions of different problems related to measurement and error calculations by using their mathematical background.

• An ability to communicate effectively. Each student should prepare two lab reports and one project report. So they learn how to prepare official project reports and experiment reports.

• An ability to use the techniques, skills and modern engineering tools necessary for engineering practice. The students learn how to use modern CAD software by drawing schematic diagrams, doing simulations by SPICE and designing a printed circuit board layout during the project lab. hours and during their spare times. They learn how to use modern measuring instruments such as digital voltmeters, ampermeters etc. in the measurement lab.

• Realistic constraints - The project chosen for implementation is a realistic one, which may be implemented by a 2nd year engineering student. Such as a DC power supply or a simple Audio Power Amplifier. The given preliminary specifications are easily realizable. And the finished product may be usable by the student.
• Economic - Students buy the necessary components of their project so they learn the current prices of some electronic components. They should choose the cheapest solution among the alternatives.
• Manufacturability - Each student should build a working circuit with box. So they learn the practical problems associated the electronic and mechanical manufacturing process.
• Health and Safety - Students are warned against the dangers of electric shock; injuries caused by mechanical tools and explained the precautions.
