Consider a multiplexer with $X$ and $Y$ as data inputs and $Z$ the as control input. $Z=0$ selects input $X$, and $Z=1$ selects input $Y$. What are the connections required to realize the 2-variable Boolean function $f=T+R$, without using any additional hardware?
answer = option A
Z'X + ZY..
Put Z = T, X = R, Y = 1 in Z'X + ZY..
= T'R + 1*T
= (T+T') (T+R)
= T + R
Can we challenge this question?
