The first revision of our PCB board, and the board our circuit was mounted on, is shown in the picture below. This revision had a few traces that were not drawn correctly and so wires had to be added and some traces cut.
The other detail with this revision was that traces were not made for the final filter design and instead space was left for this addition. With these few changes to be made, the team went back and redesigned the PCB board, as seen in Appendix D
