(b) What is the equivalent minimal Boolean expression (in sum of products form)
for the Karnaugh map given below?
Theory Explanation. |
Question 2 |
What is the minimal form of the karnaugh map shown below? Assume that X denotes a don't care term
Question 3 |
What is the equivalent Boolean expression in product-of-sums form for the Karnaugh map given below.
None of the above |
Question 4 |
Let f(x, y, z) = x' + y'x + xz be a switching function. Which one of the following is valid?
xz is a minterm of f | |
xz is an implicant of f | |
y is a prime implicant of f |
Question 5 |
The function represented by the Karnaugh map given below is:
A⋅B | |
AB+BC+CA | |
None of the above |
Question 6 |
⇒ CD+AD = D(A+C)
Question 7 |
Which function does NOT implement the Karnaugh map given below?
(w + x)y | |
xy + yw | |
None of the above |
⇒ wy + wz + xy
Question 8 |
Given the following Karnaugh map, which one of the following represents the minimal Sum-Of-Products of the map?
xy+y'z | |
wx'y'+xy+xz | |
w'x+y'z+xy | |
xz+y |
⇒ y'z + xy
Question 9 |
Minimum sum of product expression for f(w,x,y,z) shown in Karnaugh-map below is
xz+y'z | |
xz'+zx' | |
x'y+zx' | |
None of the above |
⇒ xz' + zx'
Question 10 |
The literal count of a boolean expression is the sum of the number of times each literal appears in the expression. For example, the literal count of (xy + xz') is 4. What are the minimum possible literal counts of the product-of-sum and sum-of-product representations respectively of the function given by the following Karnaugh map ? Here, X denotes "don't care"
(11, 9) | |
(9, 13) | |
(9, 10) | |
(11, 11) |
⇒ w'y' + z'wx' + xyz'
Total 8 literals are there.
For POS,
⇒ (z' + w')(z' + y')(w' + x')(x + z + w)
Total 9 literals are there.
