Question 1
|
The Boolean expression Y = (A + B’ + A’B)C’ is given by
|
AC’
|
|
|
BC’
|
|
|
C’
|
|
|
A
|
Question 1 Explanation:
Y = (A + B’ + A’B)C’
Y = AC’ + B’C’ + A’BC’
Y = (A + A’B)C’ + B’C’
Y = (A + B)C’ + B’C’
Y = AC’ + BC’ + B’C’
Y = AC’ + C'(B + B’) → B + B’ = 1
Y = AC’ + C’
Y = C’
Y = AC’ + B’C’ + A’BC’
Y = (A + A’B)C’ + B’C’
Y = (A + B)C’ + B’C’
Y = AC’ + BC’ + B’C’
Y = AC’ + C'(B + B’) → B + B’ = 1
Y = AC’ + C’
Y = C’
Correct Answer: C
Question 1 Explanation:
Y = (A + B’ + A’B)C’
Y = AC’ + B’C’ + A’BC’
Y = (A + A’B)C’ + B’C’
Y = (A + B)C’ + B’C’
Y = AC’ + BC’ + B’C’
Y = AC’ + C'(B + B’) → B + B’ = 1
Y = AC’ + C’
Y = C’
Y = AC’ + B’C’ + A’BC’
Y = (A + A’B)C’ + B’C’
Y = (A + B)C’ + B’C’
Y = AC’ + BC’ + B’C’
Y = AC’ + C'(B + B’) → B + B’ = 1
Y = AC’ + C’
Y = C’
