Task 2: 4-bit Adder/Subtractor
In the 2’s complement number system, we can accomplish the subtraction, A-B, by adding to A the 2’s complement of B; A – B = A + 2’s complement of B. This simple observation allows us to do subtraction using the same circuit used for addition. Note also that since 2’s complement of B = 1’s complement of B + 1 Therefore: A – B = A + 1’s complement of B + 1 Using the block diagram of a 4-bit adder/subtractor unit;
- Draw the corresponding logic diagram of the circuit.
- Draw the actual circuit.
In the manufacturing of an $8 000 car, how much do you estimate is spent on direct labor?
The average Japanese autoworker makes around $8 to $10 per hour and each car at Toyota has about 30 direct labor hours in it. If the average US autoworker makes $20 per hour, how many worker-hours of direct labor are in the typical American car?
If the rolls for the cold-rolling mill that produces the sheet metal used in the car cost $ 300 000, how is it that the cars can still cost less than $10 000?

An air core circular coil has 5000 turns. The inner and outer diameters are 20 and 24 cm
respectively. If a current of 2A is passed through the coil, determine the flux density inside the coil. Show complete solution.
Find the volume of the solid obtained by rotating the region bounded by the curves y=cos(x), y=0, x=0, and x=π/2 about the line y=1.
Use the Shell Method to compute the volume of the solids obtained by rotating the region enclosed by the graphs of the functions y=x^2 , y=8−x^2 and to the right of x=0.5 about the y-axis.
