essential prime implicants k map
MSRA,
See the following:
. http://www.embedded.com/columns/prog...olbox/29111968
. http://en.wikipedia.org/wiki/QuineMcCluskey_algorithm
Also, Search on "QuineMcCluskey". You'll get lots of hits. The QuineMcCluskey algorithm is concerned with the selection of "prime" and "choice" implicants for performing a logic minimization
Regards,
Kral

prime implicant wiki
implicants are individual terms of the kmap(wxyz,w'xy'z etc)... prime implicant is when these terms are combined in ways they can be combined and thereby making the variables in the term minimal.... essential prime implicants are those prime implicants which cover a particular implicant which no other term in the expression covers....

Re: Prime IMplicant & Essential Prime implicant
Final product term obtained from Kmap after combining all possible adjacent squares is known as Prime Implicant.
What are Essential Terms ?
When one Minterm can only be represented by one Prime Implicant then it is called essential term.
Why it is required ?
It helps in determining other possible simplifications for functions with multiple variables.
Can you explain it with a example?
Yes, check below
Example : Consider a function F (x, y, z, w) of 11 Minterms shown in Truth Table
