The logic operations performed by the given digital circuit is equivalent to:
The logic operations performed by the given digital circuit is equivalent to:

Options

  1. A
    AND
  2. B
    NOR
  3. C
    OR
  4. D
    NAND

Correct answer

A.
AND

Step-by-step solution

Y=Z‾=(A+B)⋅(A⋅B)=A⋅A⋅B+AB⋅BY=AB+AB=A⋅B∴ It is an AND Gate. \begin{aligned} & \mathrm{Y}=\overline{\mathrm{Z}}=(\mathrm{A}+\mathrm{B}) \cdot(\mathrm{A} \cdot \mathrm{B})=\mathrm{A} \cdot \mathrm{A} \cdot \mathrm{B}+\mathrm{AB} \cdot \mathrm{B} \\ & \mathrm{Y}=\mathrm{AB}+\mathrm{AB}=\mathrm{A} \cdot \mathrm{B} \\ & \therefore \text{ It is an } \mathrm{AND} \text{ Gate. }\end{aligned}
