Implement the inverter using nand/NOR gate

Before implementing the logic, we will have a look at the truth table of the NAND gate and the inverter.

NAND GATE

A B O
0 0 1
0 1 1
1 0 1
1 1 0

NOT GATE

A O
0 1
1 0

Fro the NAND gate truth table we can conclude the following
When both the inputs are zero(0) ==> output is 1 (same as inverter)
when both the inputs are one(1) ==> output is 0 (same as inverter)

Thus we can implement the not gate by connecting the both inputs together as shown below

Implementing inverter using NAND gate

There is another way of implementation of inverter using NAND gate , from truth table when input pin A is high (logic one) Nand gate behavious as INVERTER

Implementation of INV by NAND GATE

Before implementing the logic, we will have a look at the truth table of the NOR gate and the inverter.

NOR GATE

A B O
0 0 1
0 1 0
1 0 0
1 1 0

NOT GATE

A O
0 1
1 0

case I:
From the NOR truth table we can see that when
both the inputs are zero(0) ==> output is 1(same as inverter)
both the inputs are one (1) ==> output is 0 (same as inverter)

Inverter Implementation using NOR Gate

Case II :
second way of implementation of Inverter using Nor Gate.
