  2. Save your spreadsheet and include with your lab submission


  1. Using good old pencil and paper, write K-maps for the outputs B through G.
  2. Use the K-maps to determine the minimal Boolean function for output G (since Multisim has a gate limit).


  1. Draw the circuits for the output function G on one Multisim page. Tip: To keep things organized on the page, lay your digital inputs down vertically at the top of the page and connect a wire that extends down the length of the page. Then you can fasten connections for each output circuit. Let me know if you have questions or would like to see an example.


  1. Scan or take pictures of your K-maps and Boolean output functions
  2. Export your Multisim circuit diagram as a PNG
  3. Compile all images using the word processing program of your choice and submit via Canvas as lab4yourname.pdf. Thanks and let me know if you have any questions!
