OUTREACH

The Department of Electrical and Computer Engineering has developed some hands-on activites aimed at high-school students. These were mostly developed by ECE students. Each project has a set of instructions and explanation of the physical principles being applied, a slide presentation that could be used in a classroom, and in some cases a student handout. Instructions include parts lists and vendors. Feedback on these materials is welcome- please email Prof. Anderson at anderson@ece.osu.edu.

Audio Equalizer Student Handout

Audio Equalizer Simulator: This program is a GUI (Graphical User Interface) that can run on a PC, allows the user to select the filter type, choose resistor and capacitor values, see the frequency response of the filter, and play wave files through the filter. Some sample .wav files are included. Written by Andrew Bowser, Matthew Frankart, Teck Lee, Paul Lindstrom, and Bradley Reed.The compressed folder (900+Mb) contains: overview and instructions, a Filter GUI, a Frequency response demo, and some MATLAB files required to run the GUI

Equalizer GUI

Jeopardy! style game

Each contestant or team builds a Jeopardy-style quiz circuit. Instructions for a master circuit for the quizmaster included, along with a count-down timer. When a team presses its button, the other circuits are disable and the team has six seconds to answer the question. A Powerpoint game board is included; you can make your own questions.
