#6. Implement the following SOP (Sum of Products) logic function in all NAND gate form, and draw the resulting circuit schematic: LOGIC DESIGN & SIMPLIFICATION: Consider the truth table below (next page). From the truth table, provide the following information: (a) The logical expression as a sum-of-products, i.e., the OR-of-AND gates (b) The logical expression as a product -of-sums, i.e., the AND-of-OR gates (c) The simplified versions of the SOP expression, again using any acceptable means. (d) The circuit schematics for the simplified circuit
