Build, analyze and characterize a sound system.
Course Contents Continuation
In the EPO-1 project you and your team will design a complete audio system with "Booming Bass" extension. First, you will measure the characteristics of a 3-way loudspeaker system. You will analyze and build a power supply and a power amplifier. You will design speaker filters and the extension for a so-called "Booming Bass."

Starting from a set of specifications, you will make design choices for each part of the system. Within your team you will discuss the choices and divide the work amongst each other. To verify the choices you will make analytical calculations and numerical simulations. For this purpose you will use the mathematics and the linear circuits theory from previous and concurrent lecture courses.

You will construct the designs and test them with electrical and acoustic equipment. The measurement results are compared with the analytical and simulation results. On this basis, you will conclude to which extent the specifications have been met.

During EPO-1 you will also train team working skills. Those include working in organized meetings, making a project plan, giving oral presentations, and delivering technical reports.

Your project results will be graded on the basis of the reports, an oral presentation, and an individual oral examination.

The sound of the system will be assessed in an informal competition where all students are welcome. A jury of experts will select a winning team and award a small prize.
Study Goals
After completion of this project the student should master the following:

1) The integration in circuit analysis and design of important concepts of the theoretical lecture courses of the first semester. This includes:
- Application of resistors, capacitors, inductors, and operational amplifiers.
- Determination of transfer functions of simple circuits with those components in the time domain as well as in the frequency domain.
- Simulation of the circuits in Matlab and PSpice.
- Design of 1st and 2nd order filters.
- Design of a simple opamp voltage amplifier.
- Analysis of a power supply with transformer and diode bridge.

2) Basic skills of electronic experimentation:
- Soldering of components on a printed circuit board with the aid of a schematic.
- Effective use of a multimeter, function generator and oscilloscope.
- Interpretation of measurement results in the light of non-idealities of measurement equipment and components.

3) The basics of working in a project team. This includes:
- The planning of work,
- Organizing structured meetings,
- Writing of a project plan,
- Oral presentation, and
- Writing of engineering reports.

4) Academic skills on a basic level concerning:
- Quickly accessing a specific problem,
- Retrieving of technical information in data sheets and manuals,
- Critical assessment and citation of information.

5) A good study attitude:
- Motivation for the Electrical Engineering degree course,
- Working sufficiently hard and regularly,
- Delivering in time,
- Working sufficiently independently.

Completion of Course labs 1
The EPO-1 project will be graded on the basis of the following components:

1. Final report. Group grade; it will constitute 30% of the total grade.
2. Individual oral examination in Week 2.9. Individual grade, constituting 30% of the total grade.
3. Oral presentation skills in Week 2.9. Individual grade, constituting 20% of the total grade.
4. Intermediate reports written during the project. Group grade; it will constitute 20% of the total grade.
5. Individual tasks during the project. Individual grade, 'Pass' or 'Fail'. During the project all members should have brought to a good end at least the following tasks:
- Chairing a meeting.
- Writing minutes.
- Giving a presentation on the content of an intermediate report.
- Answering questions on the content of an intermediate report.
6. Mentoring assignment. Individual grade, 'Pass' or 'Fail'.

Required for obtaining a final grade for this course is that all the components individually have scored a 'Pass' or a grade of at least 6.

Grading during the project will be done by the tutor. The examinations at the end will be graded by a panel consisting of two or three people who are members of the academic staff of the EE program. Two of the committee members are EPO-1 tutors, amongst them your own tutor.

Assessment will be done on the basis of the study goals. You are advised to consult them from time to time in order to structure your study activities.

The deadlines in this project are hard, especially the one for the final report. Work that is handed in too late may still be graded. However, it will be subject to a penalty in such a way that the maximum obtainable grade will be a 6 ('sufficient').

Components that at the first assessment are judged as insufficient, will not be graded. To correct this, one chance will be given, after which a grade will be determined.

EPO-1 includes the mentorship. The grade of the EPO-1 project becomes not valid until all of the following mentorship requirements have been fulfilled:
- presence and active participation in the lunch meetings during the 1st semester;
- presence and active participation in the thematic meetings;
- attendance of at least 5 EWI lunch lectures or participation in the ETV symposium and attendance of 3 EWI lunch lectures;
- participation in the ETV excursion;
- participation in the social activity;
- interview with an assigned professor or researcher.
