Use a Karnaugh map to minimize the following SOP expression:
F( A, B, C, D) = \bar{A}\bar{D}+A\bar{B}\bar{D}+\bar{A}\bar{C}D+ \bar{A}C DMap the SOP expression on a 4-variable Karnaugh map. Note that the four cells in the four corners are also adjacent and they can form a group in Figure 3.6.12.
The resulting minimum SOP expression is
