ECE 2110: Circuit Theory Final Project

Designed and built a bandpass filter and steel speaker housing.

In lieu of a final exam, ECE 2110 students were assigned a final project: to design a two-channel, bandpass speaker filter using LM741 Operational Amplifiers. Two-student groups were assigned unique cutoff frequencies for which their filters had to satisfy. Each speaker system was to have a treble channel and a bass channel, each of which passed through certain input frequencies. Signal levels were to be displayed on LED bars. Students were able to satisfy these requirements however they saw fit.

Extra credit would be provided to groups who designed a speaker housing/enclosure. Designing an enclosure was not a requirement for the project, and my group was one of two who chose to design one. Me and my partner being ME majors, we wanted to employ our mechanical design skills. Almost every group presented their circuit strewn across breadboards; we produced a finished product.

Many hours were put into this project and we achieved the highest grade possible.

Selected excerpts from my final report are shown below. Please view the full, 24 page final report attached at the end of this article.
