Question

The output of an OR gate is connected to both the inputs of a NAND gate Draw the logic circuit of this combinaion of getes and write its truth table.

Solution 1

Both the inputs of the NAND gates are joined to form a single input. Therefore, it behaves like a NOT gate.

A B A + B `overline(A+B)`
0 0 0 1
0 1 1 0
1 0 1 0
1 1 1 0

 

Solution 2

Both the inputs of the NAND gates are joined to form a single input. Therefore, it behaves like a NOT gate.

A B A + B `overline(A+B)`
0 0 0 1
0 1 1 0
1 0 1 0
1 1 1 0

 

  Is there an error in this question or solution?
