Question

Implement the circuit f(x1,x2,x3,x4)=x1+(x2'*x3*x4')+(x2*x3*x4)
using NAND gates only.

Answer 1

To implement the given circuit f(x1,x2,x3,x4)=x1+(x2'*x3*x4')+(x2*x3*x4) using only NAND gates, we can break down the circuit into smaller parts and then use NAND gates to build each part.

Step-by-step explanation:

To implement the given circuit using only NAND gates, we will break down the circuit into smaller parts and then use NAND gates to build each part.

First, we can implement the expression (x2'*x3*x4') using NAND gates. We can use NAND gates to perform the AND operation and then negate the result using another NAND gate. Then, we can use a NAND gate to perform the OR operation between x1, (x2'*x3*x4'), and (x2*x3*x4) to get the final result.

Using this approach, we can implement the circuit f(x1,x2,x3,x4) = x1 + (x2'*x3*x4') + (x2*x3*x4) using only NAND gates.
