Grading
The assignment is worth 100 points: 75 points for the circuit, 15 points for the truth table, and 10 points for the Boolean expressions of the outputs.
Step 1

(75 points) - create the circuit below in either Digital Works or Logisim
A

Step 2
Attach interactive inputs to A. B, and C lines of your circuit and LEDs to the ouputs D, E, and F.
Digital Works
The interactive inputs on Digital Works will toggle between on and off, and an LED will be red if it receives a logical 1. Location of interactive input and LED on Digital Works menu

Logisim

The interactive inputs on Logisim will toggle between 0 and 1. and an LED will be red if it receives a logical 1.




Step 3
Test your circuit by toggling the interactive inputs and observe which of the LEDs light up on the three outputs. Write down which combinations of the three inputs cause specific LEDs to light up. Be sure to go through all combinations of inputs.
Digital Works
To test your circuit, click Circuit on the menu bar, then select Run. To toggle the interactive inputs use the pointer finger tool, and place the finger over the input and left click the mouse.

Logisim
To test your circuit, click Simulate on the menu bar, and make sure Simulation Enabled is checked. To toggle the interactive inputs use the pointer finger tool, and place the finger over the input and left click the mouse.

Step 4
(15 points) - create a truth table for the circuit in a Word document
- create a truth table for the circuit using a table in Microsoft Word. There will be nine columns in the truth table. One for each input signal. one for each output signal, and the last three columns will be for the LEDs (see column headings below). Use O's and l's in your truth table for the three inputs and three outputs. If an LED is red for a specific combination of inputs then put "on" in the truth table, and "off' if the LED is not red. You will need to create a separate row in the truth table for each combination of input signals.

Step 5
(10 points) - create Boolean expressions in the same Word document as the truth table Create three separate Sum of Products Boolean expressions for outputs D. E, and F.

Step 6
Submit the circuit, truth table, and Boolean expressions
Take a screen shot of your circuit and paste it into the Word document containing the truth table and Boolean expressions.
Place the Word document and the simulation file from either Digital Works or Logisim into a zip file and submit the zip file for grading.
