Q$\mathrm{.}1.$ Design a PLD using ROM for a $BCD$ to $7$ segment decoder.

Q$\mathrm{.}2.$ Implement the following using $814$ ROM:

$A={\displaystyle \underset{?}{\overset{?}{}}}(0,3,4,6)$

$B={\displaystyle \underset{?}{\overset{?}{}}}(0,1,3,7)$

$C={\displaystyle \underset{?}{\overset{?}{}}}(1,5)$

$D={\displaystyle \underset{?}{\overset{?}{}}}(0,1,4,5,7).$

I want both questions to be answered correctly with the logic diagram and proper explanation.

If answered as expected, i will give you an upvote else you will buy a downvote for you $!$

Thank you $!$
