TASK – NAND GATE EQUIVALENTS

 

 

TASK DESCRIPTION

 

Did you know that all other basic logic gates can be created from different combinations of NAND gates?  So, if you have NAND gates on hand, you can use them to create all other types!  Pretty sweet!

 

In this task, you will create a circuit that consists of several logic gates.

 

TASK

 

Create one of the NAND Equivalent circuits below and test the circuit by creating its truth table to verify that it is in fact equivalent to the corresponding basic gate.

Remember to label your inputs and your output.  Square your wires.  Be neat!

TO SUBMIT

 

Four screen captures.  One of each state.  You must also state which base gate you are doing and the max value for that gate.

Note:  You must upload your screen captures in order.
