Extracted text: Problem 2 Design an Excess-3-to-BCD code converter, requiring that all invalid input combinations give 1111 as the output code. Determine the Boolean expression of the output signals Y and Z in product-of-sums (POS) form. Only the required output signals should be shown on your answer sheet. Encircle/box your final answer. NOTE: Justify your answer by showing the circuit's truth table. Your answer should conform to the correct entries in your truth table. Inputs minterm Outputs A B D (m) W Y NOTES Required format of the truth table in Problem 2. Input entries should be listed in ascending order. No other information should be shown on the table except those indicated above. Show complete input and output entries on map. Show complete table and map grid lines. Appropriately label all groups on map.
