a) Simplify the following logic function using Karnaugh maps:

F(A, B, C, D) = ABCD + ABCD + ABCD + ABCD + ABCD + ABCD

CD\AB	AB (00)	AB (01)	AB (11)	AB (10)
CD (00)
CD ( 01)
CD (11)
CD (10)

Simplified F(A, B, C, D) =

b) In the function from part a), four don't care terms have been added:

ABCD, ABCD, ABCD, ABCD

Use the Karnaugh map to minimize the new function.

CD\AB	AB (00)	AB (01)	AB (11)	AB (10)
CD (00)
CD ( 01)
CD (11)
CD (10)

Simplified F(A, B, C, D) =
