Please teach me how to build this circuit~

Specifications: Part-2 Part-2: Description In this part of the lab we will illuminate two 7-segment displays. You will need to understand 2's Complement to determine when the values correspond to a negative or positive number. Your circuit must accept a 4-bit 2's complement input {in3, in2, ini, ing} where in3 is the most significant bit and ino is the least significant bit. The outputs of your circuit must illuminate the two 7-segment displays such that they display the decimal value of the input. Part-2: User Interface You are provided an interface file lab2_part2.dig, start Part-2 from this file. You are not permitted to edit the content inside the dotted lines rectangle. Interface (do not edit the content inside this bar Inputs int Outputs: sign seg, 8 8 8 sign. Human readable value decimal Figure: Lab2_part2.dig Interface Part-2: Example In the figure above, the input is {in3, in2, ini, ing} = {0, 0, 1, 1} which is the 2's complement binary representation of the value 3. Note: only the middle segment (sign_g) on the left display will be illuminated for negative values.
