Question

The diodes in the circuit shown are ideal. A voltage of 0 V represents logic 0 and +5 V represents logic . The logic function Z realized by the circuit for logic inputs X and Y is

• A. $Z=\overline{XY}$
• B. $Z=XY$
• C. $Z=\overline{X+Y}$
• D. $Z=X=Y$

Answer 1

The correct option is B $Z=XY$

$$\begin{array}{ccc}X& Y& Z\\ 0& 0& 0\\ 0& 1& 0\\ 1& 0& 0\\ 1& 1& 1\end{array}$$
