Physics - Semiconductors Question with Solution | TestHub

The output of an AND gate with inputs $\mathrm{A}$ and $\mathrm{B}$ is given by $\mathrm{A}\cdot \mathrm{B}$.

When this output is passed through a NOT gate in series, it gets inverted.

The final output $\mathrm{Y}$ is the complement of the AND gate output, which is $\mathrm{Y}=\overline{\mathrm{A}\cdot \mathrm{B}}$.

This combination is known as a NAND gate.

Answer: $\overline{\mathrm{A}\cdot \mathrm{B}}$
