3. Draw the logic diagram of the SOP minimized circuit 4. Use De Morgan's theorems to express the simplest SOP in terms of NAND operators. 5. Use the Karnaugh map method to find the simplest product-of-sums (POS) expression of the function Y(A, B, C, D). 6. Draw the logic diagram of the circuit that implements the POS minimized expression. Analyze the circuit that implements the POS minimized expression and determine its truth table A B C D Y 0 0 0 0 0 1 1 0 0 0 1 0 2 0 0 1 0 1 3 0 0 1 1 0 4 0 1 0 0 0 5 0 1 0 1 0 6 0 1 1 0 0 7 0 1 1 1 0 8 1 0 0 0 1 9 1 0 0 1 1 10 1 0 1 0 1 11 1 0 1 1 1 12 1 1 0 0 0 13 1 1 0 1 0 14 1 1 1 0 1 15 1 1 1 1 0 Table 5.2.1: Truth table of Part II logic function
