created a digital guitar tuner that takes output from an electric guitar and
helps the user tune it to “Standard E” tuning.
user interacts with the device by pushing buttons to select which string he or
she is tuning. The user then plucks the string and the device displays if the
string is too high frequency (sharp), too low frequency (flat), or within 0.5%
of the desired value. We chose this project because both of us play guitar and
don’t want to pay a lot for tuners. We were also very interested in applying
some of the Digital Signal Processing (DSP) and analog amplification principles
we learned in some of our other classes. This project gave us the opportunity
to test out these principles in a real-world design.
