## Example of 4 Variable K-Map|Don't Care Condition.

By on 23:31

Now I discuss Karnaugh Map of 4 variables(5 is also possible) and also its Don't Care Condition.

Syntax of 4 Variable K-Map:-

Q)Z=Σ(0,1,3,5,10,11,12,13,15)...SOP

y=a'b'c'+a'b'd+bc'd+abc'+acd+ab'c

Q)Z=Σ(0,2,5,8,7,10,13,15)

y=bd+b'd'(XOR)

Q)Z=Σ(4,1,9,6,12,14,11)

y=bd'+ab'd+a'b'd

Q)S=Π(1,5,7,3,7,13,15)..POS

y=(a'+d').(b'+d')

Don't Care Condition(K-Map):-We use Don't care condition in K-Map because to make a group of 2 variable.

y=Σ(0,1,3,5,9,12)+Σd(2,4,6,7)

y=a'+bc'd'+b'c'd

2. it is difficult to understand what you try to explain to the viewers.

3. How many don't care terms are allowed to form a group of 2,4,8,16 terms?

4. At least one freah 1 is needed im any group of 2, 4, 8,16 but group must be maximum.
