BOOLEAN ALGEBRA 2

In Boolean Algebra ,A'' =

• 1

• A

• 0

• A'

In Boolean Algebra , A + BC =

• (A+B)(A+C)

• (A'+B)(A'+C)

• A' + B'C'

• A+ B' + C"

(A + B')' is also equals to

• AB

• A'B

• A B'

• None

The expression AB + BC can be written in canonical form as

• A'BC + AB'C + ABC'+ A'B'C

• ABC + AB'C' + A'BC'

• ABC + ABC' + A'BC

• None

The expression (A+B).(B+C) can be written in canonical form as

• (A' + B+C).(A+B+C').(A'+B+C)

• (A + B'+C).(A+B+C').(A'+B+C)

• (A + B+C).(A+B+C').(A'+B+C)

• (A '+ B'+C).(A+B+C').(A'+B+C)

The minterms (0,3,4) can be written in expression as

• ABC+AB'C+A'B'C'

• (A'+B'+C').(A'+B+C).(A+B'+C')

• (A+B+C).(A'+B+C).(A+B'+C')

• A'B'C'+A'BC+AB'C'

The maxterms (1,6,7) can be written as

• (A'+B'+C).(A+B+C').(A+B+C)

• (A+B+C').(A'+B'+C).(A'+B'+C')

• ABC'+A'B'C+A'B'C'

• None
