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
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
2. to avoid real or perceived conflicts of
interest whenever possible, and to disclose them to affected parties when they
Our guitar tuner was built for our own
education and enjoyment for ECE 476. Therefore there are no potential conflicts
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
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
