Our guitar tuner conformed to our expectations. When we started we were not sure what kind of stability and accuracy we could achieve in our tuner. As we continued to improve the device we became more and more impressed and satisfied with our tuners performance.


If we were to do this over again we would want to investigate some of the advantages and disadvantages of a fasters sampling frequency. While developing our tuner we did not want to sample faster than we could compute the frequency. However, once we know what is involved in frequency calculation we could have attempted to sample faster to improve accuracy.


We developed the basic structure for our design by researching past ECE 476 projects as well as researching online. Some good sources of information were online newsgroups where people were able to contribute there ideas on guitar tuners freely. Because people in the newsgroups were anonymous and were offering their information to help people building devices similar to ours we assumed to that the basic very low-level design information was not copyrighted. We wrote all the code in our device and we developed all the specifics of our design ourselves with some help from the TAs.


IEEE Code of Ethics Considerations

1.      to accept responsibility in making engineering decisions consistent with the safety, health and welfare of the public, and to disclose promptly factors that might endanger the public or the environment;

Our project represents very little of a danger to health and welfare of the public. The only dangers, which would arise from someone reassembling our circuits, would be and overheated or blown circuit element.

2.      to avoid real or perceived conflicts of interest whenever possible, and to disclose them to affected parties when they do exist;

Our guitar tuner was built for our own education and enjoyment for ECE 476. Therefore there are no potential conflicts of interest.

3.      to be honest and realistic in stating claims or estimates based on available data;

We were honest and realistic to the best of our knowledge.

4.      to reject bribery in all its forms;

Unfortunately this was not applicable to our project.

5.      to improve the understanding of technology, its appropriate application, and potential consequences;

We gained understanding in DSP and analog hardware design. We therefore furthered our own understanding of technology.

6.      to maintain and improve our technical competence and to undertake technological tasks for others only if qualified by training or experience, or after full disclosure of pertinent limitations;

We improved our technical competence through design and testing. We were well aware of our limitations as junior ECE students who havenít had a lot of experience with design.

7.      to seek, accept, and offer honest criticism of technical work, to acknowledge and correct errors, and to credit properly the contributions of others;

We mentioned those who helped us in the report and were always honest with one another about project problems. We freely discussed our design with others creating guitar tuners.

8.      to treat fairly all persons regardless of such factors as race, religion, gender, disability, age, or national origin;

There was no discrimination of any kind involved in our project.

9.      to avoid injuring others, their property, reputation, or employment by false or malicious action;

We did not commit any false or malicious action during the course of this project.

10.  to assist colleagues and co-workers in their professional development and to support them in following this code of ethics.

We always helped people that asked questions of us thus helping them to develop a further understand of electrical engineering.
