MAIN QUESTIONS 1. Figure 1 shows a full adder combinational logic circuit which is used to add three bits and produce a sum and carry output. A full adder is an important component in binary addition. IS Full Adder Cin Cout Figure 1 The rules for binary output are shown below: 0 +0 = 0 0+1 = 1 1+0 = 1 1+1 = 0, carry 1 1+1 +1 = 1, carry 1 (a) Complete the truth table for each combination below. Output Input Cin B AS Cout 1 1 1 1 1 1 1 1 1 1 1 Table 1 (b) By applying minimisation techniques to your answer for part (a), derive the minimum logic expression for each output. Show your methodology clearly in your answer. (c) Using your answer to part (b), draw the minimised circuit for S using IEC symbols. (d) The engineer would like to implement the minimised circuit using only NAND gates. Using Boolean algebra, derive and draw a minimal NAND only circuit for Cout. You should show the steps required to find the NAND only minimal circuit.
