A logical expression from a logical circuit
We will find logical gates like AND, OR, NOT, X-OR, X-NOR, NAND, NOR. From these, we have to write proper expressions from each gate output and have to find out a combined output finally.From here we have to write the expression outputs from each gate. Finally, we will get the final expression for the total circuit.
A and B are inputs of AND gate. So the output is AB. Next, B and C are the input of the OR gate. So the output is B+C. And next these tow are going from a NAND gate.
In the below C, A is going from AND gate. So the output is A͞C. Finally, both outputs are passing from an OR gate.
We know from De Morgan's law,
Ā+ B̄ = A͞B
So the simplification of that expression
