Question

find the complement of :F1=AB'+C'D'​

Answer 1

Answer:

(A'+B).(C+D)

Explanation:

Complement of F1 will be  ~(F1) will be  ~(AB' +C'D')

Keeping De-Morgan's theorems in mind we'll have,

~(AB' +C'D')

=  ~(AB') . ~(C'D')

= (A'+B).(C+D)

Answer 2

Answer:

AB(C'+C)(D'+D) + (A'+A)BC'D' + A'BC(D'+D) + ( A'+A)(B'+B)C'D ... Find the complement of the following expressions. 1) F1 = AB' + A'B.
