Need 2 different variations answers and with explanation please. Thank you. PART 4: Using the custom circuits you built in Parts 1-3, built a 4 bit 2's Complement multiplier that usesthe inversion method discussed in class.HINTS: INVERSION METHOD:1) If input A is negative, invert it. If input A is positive, leave it alone.2) If input B is negative, invert it. If input B is positive, leave it alone.3) Multiply A and B.4) If both A and B originally had the same sign (both positive or both negative), do nothing.5) If A and B originally had different signs (one was positive, the other negative), invert the product. 4 bit 2's Complement MultiplierINPUT A: 4 bit 2's Complement numberINPUT B: 4 bit 2's Complement numberOUTPUT: the product of A x B represented as a 8 bit 2's Complement numberYou are only allowed to use the basic gates: NOT, AND, OR, XOR. You may however, use these basic gatesto build your own custom circuits (i.e. Adder). You are NOT ALLOWED to use Logisim built in circuits.Each custom circuit is to be implemented as a sub-circuit.PART 1: Build a 4 bit controlled 2's Complement InverterPART 2: Build a 8 bit controlled 2's Complement InverterPART 3: Build a 4 Bit UNSIGNED MultiplierA: 4 Bit InputB: 4 Bit InputMultiplier0000 000O

Solution: Part 4 Thank you ... Please feel free to ask the doubts if you have any will solved it ....
