Final Report Guidelines
Specific Requirements on Contents and Structure of Final Report¶
In this document, specific instructions for the structure and contents of the final report will be given.
Note that to prepare the final report, your mentorate group efficiently reuses and then adjusts the relevant parts from your team’s intermediate reports.
The final report should not exceed 40 A4 pages (this is excluding the appendices).
Final Report Structure¶
The final report should focus on the sound system that your mentorate group finally built. You can efficiently reuse some parts of the previous intermediate reports to prepare the final report. Your mentorate group can report on the Booming Bass design (if executed). It is important to include a final acoustic characterization of the total system. Also, proper prologue sections (such as table of contents and introduction) and epilogue section(s) (such as bibliography and appendices) should be added.
The final report could then be structured as follows.
Cover and title page. Your cover page shall include the group name as well as the subteams including the related names of the students for each subteam. Do not include the student numbers in the document.

Final report checklist¶
Here follows a checklist with items that are expected to be included in your EE1L1 IP-1 Final report. Experience shows that these items are covered in the Final reports with a large degree of variability. Please note that these items are not new requirements, they are just a selection of already explicitly formulated requirements in the manual, in particular in the reporting templates (the rubrics, included). The reason for singling these items out here is to support you in preparing an as much as possible complete and well-argued report.
The checklist contains items that should have already been present in the intermediate reports. There are two new items: the general Final report introduction and, optionally, the description of the booming bass solution.
A bonus/malus system is built in the checklist. The bonus/malus points must be regarded as maximums, with full malus being applied when the relevant item is missing completely and the full bonus being awarded when the relevant item is dealt with, and at adequate level. Fractions of the bonus/malus points may be assigned, as applicable.
Introduction¶
The complete functional system of the audio system is presented and commented. Malus: -0.5 points
Power Supply Analysis¶
Measurements, including waveform snapshots; comparison of the measured results with simulated and/or analytic results, including an attempt to explain possible discrepancies. Malus: -0.25 points
Loudspeaker Analysis¶
The equivalent circuit for simulating Model 1 in Figure 5 and Model 2 according to Equation (8) (both in Chapter 4. Speaker Impedance) is developed and discussed; simulated results are also provided. Malus: -0.25 points
Comparison between measured and simulated data, including an attempt to explain possible discrepancies. Bonus: 0.25 points
Passive Filter Design¶
The partial simulated results (for the bass, mid and tweeter parts) are added up and the flat total result is illustrated (assuming an identical electric acoustic transfer); deviations from the linear behaviour are discussed and, possibly, commented. Malus: -0.25 points
Comparison between measured, simulated and/or analytic results, including an attempt to explain possible discrepancies. Bonus: 0.25 points
Power Amplifier Design¶
Simulation results. Malus: -0.25 points
Comparison between measured, simulated and/or analytic results, including an attempt to explain possible discrepancies. Malus: -0.25 points
