Describe the output.
Question 2
Start with 2 inputs.
Design a circuit, so that the output follows the truth table below.
Use MS Word>>Insert>>Screenshot>>Screen Clipping>> and paste your work below.
Question 3
Start with 2 inputs.
Add two logic gates so that the output follows the truth table below.
Use NOT gate and NAND gate:
Question 4
Start with 1 input. Use only NAND gate and make the output following the truth table below.
Compare your work to NOT gate and comment on the difference.
Question 5
NAND gate is referred as universal gate as any other logic gate can be built using NAND gate only. *Note: this question is very challenging!
(a) Try to build an AND gate using only NAND gate.
Hint: NAND gate is NOT gate + AND gate. So, AND gate is NOT gate + NAND gate.
(b) Try to build an NOR gate using only NAND gate.
Hint: NOR gate = (NOT Input 1) AND (NOT Input 2)
