CS-343 Assignment 3

DUE September 22


Send the following three circuits as attachments to a single email message to me by midnight on the Due Date. The Subject line of your mail must say, "CSCI-343 Assignment 3" and your mail must start with your name and ID number.

Do not send me a Word document. Attach three .ckt files to your email message.


  1. Using only AND, OR, and Inverter gates, construct a Full Adder using CircuitMaker. Use switches for the three inputs, and LEDs for the two outputs. LEDs (light emitting diodes) appear as "Logic Display" in the Devices->Hotkeys1 menu. Simulate your design to make sure it works correctly.

  2. Repeat Question 1 for a Decoder with 2 inputs.

  3. Repeat Question 1 for a Multiplexer with 2 control inputs (and 4 data inputs).
