7 Design a combinational circuit that has four inputs, A, B, and C and one output, Y. The output Y is HIGH ONLY when the decimal equivalent of the input is greater than 2. Derive the truth table for this combinational circuit. [5 marks] (b) Write the Boolean expression for the output, Y. Using Karnaugh mapping technique, derive the simplified expression for the output, Y. [11 marks] (c) Draw the logic circuit implementation of Y in (b) using minimum number of gates. [2 marks]
