Studdy Solution

STEP 1

Assumptions1. The Boolean Algebra expression is Y=AˉBˉC+ABˉCˉ+AˉBˉCˉY=\bar{A} \bar{B} C+A \bar{B} \bar{C}+\bar{A} \bar{B} \bar{C}. . We are asked to simplify the expression in either SOP (Sum of Products) form or POS (Product ofums) form.

STEP 2

First, we notice that there are common terms in the expression. We can factor out these common terms to simplify the expression. The common terms are AˉBˉ\bar{A} \bar{B}.
Y=AˉBˉ(C+Cˉ)+ABˉCˉY=\bar{A} \bar{B} (C+\bar{C})+A \bar{B} \bar{C}

STEP 3

Now, we know that in Boolean Algebra, C+CˉC+\bar{C} is always equal to1. This is because it represents the sum of a variable and its negation, which is always true.
Y=AˉBˉ1+ABˉCˉY=\bar{A} \bar{B} \cdot1 + A \bar{B} \bar{C}

STEP 4

The multiplication of any term with1 is the term itself. So, we can simplify the expression further.
Y=AˉBˉ+ABˉCˉY=\bar{A} \bar{B} + A \bar{B} \bar{C}

STEP 5

Next, we notice that the term Bˉ\bar{B} is common in both terms. We can factor this out.
Y=Bˉ(Aˉ+ACˉ)Y=\bar{B} (\bar{A} + A \bar{C})

STEP 6

Again, we know that in Boolean Algebra, Aˉ+A\bar{A} + A is always equal to1. This is because it represents the sum of a variable and its negation, which is always true.
Y=Bˉ(1+Cˉ)Y=\bar{B} (1 + \bar{C})

STEP 7

In Boolean Algebra, the sum of any term with1 is always1. This is because it represents the sum of a variable and the truth value, which is always true.
Y=Bˉ1Y=\bar{B} \cdot1

STEP 8

Finally, the multiplication of any term with1 is the term itself. So, we can simplify the expression to its simplest form.
Y=BˉY=\bar{B}So, the simplified Boolean Algebra expression is Y=BˉY=\bar{B}.
