Answer: A NAND gate is a universal gate, meaning that any other gate can be created using only NAND gates. To create an OR gate using NAND gates, we can use the following circuit:
A B
\ /
\/
---
| |
---
C D
\ /
\/
---
| |
---
OR
In this circuit, A and B are the inputs, and C and D are the outputs of the two NAND gates. The final output is OR. The truth table for this circuit would be:
A B C D OR
0 0 1 1 1
0 1 1 0 1
1 0 1 0 1
1 1 0 0 0
Here, ‘0’ represents a low or false signal, and ‘1’ represents a high or true signal. The truth table shows that the output of the OR gate (OR) is high (1) when either or both of its inputs (A or B) are high (1). It is low (0) only when both its inputs are low (0).
