The order of the inputs on the truth table is impor- tant. The order is (A, B, C, D) Yu l show an output column for each operator (AND, OR NOT). Note that you will assume there is no NOR gate in the circuit and will not simplify the expression in this question. Draw the circuit of the above expression, assuming that single-rail inputs are available and with AND, OR, NOT gates. How many gate levels does the original expression have? Then convert the original circuit (with AND, OR, NOT) to a minimal circuit with only NAND gates, as done in class. 4) Consider the following minterm list fa, b, c, d)m(0, 1, 6, 7, 8,9, 14, 15) Obtain the minimal SOP expression by going through the steps shown in class. Draw the corresponding 2-level AND-OR gate network, assuming that single-rail inputs are avail able. By using the minterm list in Question (4) above, obtain the minimal product-of-sums expres- sion by using the Kamaugh-map technique. Draw the corresponding 2-level OR-AND gate net- work, assuming that single-rail inputs are available. 6) Develop a "majority" circuit with four single-rail inputs, A, B, C, D, and one output. It works such that if three or more inputs are 1, the output is1. Otherwise, (a inputs are 0 or one input is I or two inputs are I), the output is 0 Majority
