The figure gives a system of logic gates. From the study of the truth table, it can be found that to produce a high output $(1)$ at $R$ , we must have

Options:

Answer:

Solution:

From figure

$[\bar{(\bar{X} + Y) + X \bar{Y}}] = R$

$R = (\bar{\bar{X} + Y}) \cdot (\bar{X \bar{Y}})$

$R = (\bar{X} \bar{Y}) (\bar{X} + \bar{Y})$

$R = X \bar{Y} (\bar{X} + Y)$

$R = X \bar{X} \bar{Y} + X \bar{Y}$

$R = X \bar{Y}$

i.e., when $\begin{matrix} X = 1 \\ Y = 0 \end{matrix}] \Rightarrow R = 1$
