GATE EC 2007 Set 1 Q44 — Sequential Circuits

The following binary values were applied to the $\mathrm{X}$ and $\mathrm{Y}$ inputs of the NAND latch shown in the figure in the sequence indicated below:
$\mathrm{X}=0, \mathrm{Y}=1 ; \quad \mathrm{X}=0, \mathrm{Y}=0 ; \quad \mathrm{X}=1, \mathrm{Y}=1 \text{.}$

The corresponding stable $\mathrm{P}, \mathrm{Q}$ outputs will be

Choose one optionA

\mathrm{P}=1, \mathrm{Q}=0 ; \qquad \mathrm{P}=1, \mathrm{Q}=0 ; \qquad \qquad \qquad \qquad \mathrm{P}=1, \mathrm{Q}=0

\mathrm{P}=0, \mathrm{Q}=1

\mathrm{P}=1, \mathrm{Q}=0 ; \qquad \mathrm{P}=0, \mathrm{Q}=1

\mathrm{P}=0, \mathrm{Q}=1; \; \quad \mathrm{P}=0, \mathrm{Q}=1

\mathrm{P}=1, \mathrm{Q}=0 ; \qquad \mathrm{P}=1, \mathrm{Q}=1 ; \qquad \qquad \qquad \qquad\mathrm{P}=1, \mathrm{Q}=0

\mathrm{P}=0, \mathrm{Q}=1

\mathrm{P}=1, \mathrm{Q}=0 ; \qquad \mathrm{P}=1, \mathrm{Q}=1 ; \qquad \qquad \qquad \qquad \mathrm{P}=1, \mathrm{Q}=1
