ROLLING THE MAP
Consider
a Karnaugh map as shown in Fig. 2.22.
The
Boolean equation for two pairs is
The
above expression shall also be obtained as follows:
If
we see the above Fig. 2.22 and rolling it, the left side touches the right side
and the two pairs actually from a quad as shown in Fig.2.23.
By
visualizing as a quad, we can drop A, 
, C and 
, the
Boolean equation can be written as
Y = B
