I have a couple questions (#) for my hw, below is what I worked on with things to help better understand the questions
(-[_]) = "not" [_]
AB = A*B = A & B
A+B = A or B
Given: Boolean Theorems T1-T12
Simplify each Boolean Theorem
(a) Y = (-A)BC + (-A)B(-C)
(b) Y = (-A)(-B)(-C) + A(-B)
(c) Y = ABC(-D) + A(-B)(-C)(-D) + (-(A + B + C + D))
Work:
(a): = (-A)B; T5 Complements
(b): = How should I begin this process?
Using the truth tables I was able to derive
=(-A)(-B)(-C) + A(-B)(-C) + A(-B)C
= (-A)(-B)(-C) + A(-B)C = (-B); using T5
= A(-B)(-C) + A(-B)C = A(-B); using T5
=(-B) + A(-B);
Though I'm not even sure this is right
(1) How should I simplify if I didn't use the truth table?
(c): Used the same logic as (b)
= (-B)(-C)(-D) + (-D)
Some needed clarification:
(2) B(-B) = 0; T5, but is it possible with multiple variables? AB+A(-B) = A?
(3) Can we use single variable theorem (T1-T5) with multiple variables?
(4) AB + (-A)(-B)D; Can this be simplified more?
Note:
Let me know if I need to explain more on a certain area (i.e. if you need all the boolean theorems)
Give me simple equations to solve to better convey an idea
Let me also know if you prefer the work to be at the top of the page or bottom if you care
