Design a circuit which will add a 4-bit binary number to a 5-bit binary number. Use five full adders.

4 bit 2’s Complement Multiplier INPUT A: 4 bit 2’s Complement number INPUT B: 4 bit 2’s Complement number OUTPUT: the product of A x B represented as a 8 bit 2’s Complement number You are only allowed to use the basic gates: NOT, AND, OR, XOR. You may however, use these basic gates to build your own custom circuits (i.e. Adder). You are NOT ALLOWED to use Logisim’s built in circuits. Each custom circuit is to be implemented as a sub-circuit as discussed in class. PART 1: Build a 4 bit controlled 2’s Complement Inverter as a subcircuit named 4BitInverter

2. Given the logic symbol for the 7485 IC (4-bit comparator). Use it to compare two binary numbers of 12 bit.

Find the maxterm expansion of the truth table and develop a digital circuit that works with the given truth table.
