Specifications: Part-2Part-2: DescriptionIn this part of the lab, we will illuminate two 7-segment displays. You will need to understand 2's Complement todetermine when the input 4-bit binary number corresponds to a negative or positive number. To understand how anLED display works in Digital, please refer to the playWithLED_Display.dig file provided. You should play withdifferent input combinations to see how it influences the LED Display value. In the screenshot below, note how I wasable to generate the display of “3” on the Hex display by lighting up only certain input wires to the unit. Here is a picture of how the different segments light up to produce the different displays: Note in the picture above that we showed displays only from 0-8 since in 4-bit 2s complement representation, 8 is thelargest modulus value you can represent (the range of integers would be -8 to +7).Your circuit in Part-2 must accept a 4-bit 2's complement input {in3, in2, in1, in0} where in3 is the most…
