For $F(A,B,C,D)=B^{\text{'}}D+A^{\text{'}}D+B{D}^{\text{'}}$

a$)$ Draw the truth table for function $F.$

b$)$ Find the product of sum $($POS$)$ representation of the function

c$)$ Find the sum of product $($SOP$)$ representation of the function

d$)$ Find simplified Boolean function with minimum number of literals by using Boolean axioms and theorems

CAN YOU EXPLAIN THE SOP AND POS DIFFERENCE BETWEEN THEIR SIGN for example X$1\text{'}$ is equal to $1$ or $0$ in SOP
