Unformatted text preview: F 3 =xy+x’y’ Design the circuit with a decoder and some external gates. 4. Using 4 exclusive-OR gates and a four bit full adder, construct a 4-bit parallel adder/subtractor. Use an input select variable V so that when V=0, the circuit adds and when V=1, the circuit subtracts. (Use 2’s complement for subtraction)...
