5 Variable Karnaugh Map Solution

Simplify the Boolean function
F(A,B,C,D,E)  = Σ (0,2,4,6,9,11,13,15,17,21,25,27,29,31)

Writing decimals in binary,

 Decimal    A    B    C    D    E
     0           0    0     0    0    0
     2           0    0     0    1    0
     4           0    0     1    0    0
     6           0    0     1    1    0
     9           0    1     0    0    1
     11         0    1     0    1    1  
     13         0    1     1    0    1
     15         0    1     1    1    1
     17         1    0     0    0    1
     21         1    0     1    0    1
     25         1    1     0    0    1
     27         1    1     0    1    1
     29         1    1     1    0    1
     31         1    1     1    1    1

Construct two Karnaugh maps for variables A,B,C and D when  E=0 and E=1




From Karnaugh map E=0,  F0 = A'B'E'

From Karnaugh map E=1,  F1 = BE+ AD'E

F  =   F0+  F1

F   =    A'B'E'   +  BE  +   AD'E

  2. Think of it as two different 4 variable Karnaugh Map problems. First solve for ABCD for rows with E=0. Secondly, solve for ABCD for rows with E=1.Hence two Karnaugh Maps
