Physics - Semiconductors Question with Solution | TestHub

A combination of logic gates is as shown in figure. ' $P$ ', ' $Q$ ', ' $R$ ' and ' $\mathrm{S}$ ' are the inputs and ' $\mathrm{X}$ ', ' $\mathrm{Y}$ ' and ' $\mathrm{Z}$ ' are outputs. When inputs $\mathrm{P}$ and $\mathrm{R}$ are 'low' and $\mathrm{Q}$ and $\mathrm{S}$ are 'high', the outputs $\mathrm{X},\mathrm{Y}$ and $\mathrm{Z}$ are respectively
