Q1
For the logic function
F(A,B,C,D,E)=m(0,2,6,7,8,10,11,12,13,14,16,18,19,29,30)+d(4,9,21)
F(A, B, C, D, E)=\sum m(0,2,6,7,8,10,11,12,13,14,16,18,19,29,30)+\sum d(4,9,21)


Find the minimum sum-of-products expression for FF, using the QuineMcCluskey method.

Answer
F(A,B,C,D,E)=ABC+ADE+ABCD+ABCD+ABCDF(A, B, C, D, E) = \overline{A} \overline{B} \overline{C} + \overline{A} \overline{D} \overline{E} + A\overline{B}C\overline{D} + ABC\overline{D} + AB\overline{C}D
Solution
a
Grouping Minterms: Group the minterms based on the number of 1s in their binary representation
b
Combining Groups: Combine minterms within groups that differ by only one bit to form prime implicants
c
Prime Implicant Chart: Create a prime implicant chart to identify essential prime implicants and to cover all minterms
d
Selecting Prime Implicants: Select the essential prime implicants and the minimum number of non-essential prime implicants needed to cover all minterms
e
Minimum Expression: Write down the sum-of-products expression using the selected prime implicants
Key Concept
The Quine-McCluskey method is a tabular method for minimizing Boolean functions to find the most simplified sum-of-products expression.
Explanation
The minimum sum-of-products expression for the given logic function FF is obtained by identifying essential prime implicants and selecting the minimum number of non-essential prime implicants to cover all minterms, resulting in the simplified expression.
