Logic circuits:pos k-map

[nafnaf]

example1

find the POS of F(a,b,c,d) = Ʃ(1,3,6,9)

what should i consider in grouping? 0's or 1's?


example 2
find the POS of F(a,b,c,d) = ∏(0,1,6,8)

what should i consider in grouping? 0's or 1's?


im confused
kindly explain to me guys


thanks

nafnaf,

find the POS of F(a,b,c,d) = Ʃ(1,3,6,9)

Why do you show a summation symbol (Ʃ) for the product of sums (POS)? You should define an uncommon acronym at least once before using it.

what should i consider in grouping? 0's or 1's?

What does the above statement mean?

thats a sample Q in our quiz


what should i consider in grouping? 0's or 1's?

in SOP i will group 1's
in POS i will group 0's

is this correct???

nafnaf,

You must be cognizant of the fact that those in this forum have not taken the course you are taking, or are familiar with your study material and nomenclature. We do know how to simplify terms using Boolean algebra or Karnaugh maps. I, for one, do not know what you mean by grouping by ones or zeros. Perhaps you can give an example. You have not answered the question I asked about the summation symbol.

thank sfor reply

but i already figured out what i have searching

thanks

example1

find the POS of F(a,b,c,d) = Ʃ(1,3,6,9)

The numbers enclosed in the parenthesis represent the minterms with '1' as their output.

example 2

find the POS of F(a,b,c,d) = ∏(0,1,6,8)

The numbers enclosed in the parenthesis represent the minterms with '0' as their output.

I think what you need is the Boolean equation.

Draw the KMAP again and now fill in 1's and 0's.

From there, derive the Boolean equation.

Study well my friend.

thanks moewth08 thats what im talking about

but now im trying to solve a 6 variable k map using quine mcklusky and its so long

nafnaf,

You might want this program. http://sontrak.com/

thanks sir ratch

i think it would help me a lot

thanks moewth08 thats what im talking about

but now im trying to solve a 6 variable k map using quine mcklusky and its so long

How is this?

I think it should be a 6 variable equation using quine?

It's really long. Just be patient. The link of Ratch is good. I downloaded the program too. I might need it for minimizations or maybe for drawing logic gates for presentation purposes.

It's meowth08
