Groups may wrap around the table. We will use the form on the right.

Note the sequence of numbers across the top of the k map simplification. It is not in binary sequence which would be 00, 01, 10, It is 00, 01, 11 10, which is Gray code sequence.

Logic circuit simplification (SOP and POS)

Gray code sequence only changes one binary bit as we go from one k map simplification to the next in the sequence, unlike binary. That means that adjacent cells will only vary k map simplification one bit, or Boolean variable. This is what we need to organize the outputs of a logic function so that we may view commonality.

Moreover, the column and row headings must be in Gray code order, or the map will not work as a Karnaugh map.

k map simplification Select and Populate K-Map From Step 1, we know the number of input variables involved in the logical expression from which size of the K-map required will be decided. Further, we also know the number of such K-maps required to design the desired system as the number of output variables would also be known definitely.

The procedure is to be repeated for every single output variable. k map simplification

Form the Groups K-map simplification can also be referred to as the "simplification by grouping" technique as it k map simplification relies on the formation of clusters. The process has to be initiated by grouping the bits which lie in adjacent cells such that the group formed contains the maximum number of selected bits.

A truth table is a list of the inputs A, B on the left k map simplification the corresponding output F on the right. See Figure 1 showing a 2 variable truth table and corresponding K-Map.

This ordering ensures that only one bit changes for any adjacent cell.

It is logical adjacency that makes Boolean simplification possible. That means that adjacent cells will only vary by one bit, or Boolean variable.

Logic Simplification With Karnaugh Maps

This is what we need to organize the outputs of a logic function so that we may view commonality. Moreover, the column and row headings must be in Gray code order, or the map will not work as a Karnaugh map.

Cells sharing common Boolean variables would no longer be adjacent, nor show k map simplification patterns. Adjacent cells vary by only one k map simplification because a Gray code sequence varies by only one bit.

K map simplification Gray Code If we sketch our own Karnaugh maps, we need to generate Gray code for any size map that we may use. This is how we generate Gray code of any size.

Note that the Gray code sequence, above right, only varies by one bit as we go down the k map simplification, or bottom to top up the list.
