The Boolean expression B⊕E is a simplified version of expression ABE + BCDE+ BC D E + A B D E + B C D E + A B D E then which of the following choice is correct?
- don't care conditions doesn't exist
- don't care conditions exist
- d( 16, 18, 20, 23, 27, 29) is the set of don't care conditions
- d( 16, 20, 22, 27, 29) is the set of don't care conditions
Answer : Option C
Explanation :
Reduced form of the given expression is B ⊕ E:
A BE + BCDE + B C D E + A B D E + B C D E + A B D E
Now we draw a K-map for 5 variables :
Since we can realize B ⊕ E i.e. BE + B E as shown above, the K-map drawn should have don't care conditions that will be taken into consideration and will be grouped; along with l's.
∴ We have don't care conditions with a set d( 16, 20, 22, 27, 29).
