Use Logisim to model the circuit exercises.

For all circuits label inputs as A and B and the output as OUT.

Put a title at the top of each circuit, a brief description, and your name.

Add text-based question responses, truth tables, etc. to this document and submit with .circ files.

.

1. (4 pts) Build an OR Gate using three 2-input NAND gates. Turn in the circuit (.circ file) and corresponding Truth Table.
2. (4 pts) Build a NOR Gate using four 2-input NAND gates. Turn in the circuit (.circ file) and corresponding Truth Table.
3. (3 pts) Why use NAND gates to produce the other types of gates? Research and provide your findings why they are more widely used than other TTL and CMOS gates.
