**Construct the Karnaugh map for the following function, and find the function in sum of product form. Draw the resultant logic diagram. F (A, B, C, D): Σ (0, 2, 4, 5, 6, 7, 8, 10, 13, 15). 5m Dec2007**

** **K-Map for F is:

Thus, the simplified equations for F (A, B, C, D) = Σ (0, 2, 4, 5, 6, 7, 8, 10, 13, 15)

are:

F = B|CD+|B|D+|AB

**Logic diagram:-**

(b) **Draw the logic diagram for a 4 x 4 random access memory. Assume that the cells of RAM are made of R – S flip-flop. 5**
