2's Complement: Design a circuit to add or subtract two 4-bit binary numbers. For the subtraction, do a conversion from a positive 4-bit binary number to its corresponding negative in 2's complement representation (for example convert +4 to -4 in 2's complement). There should be a control signal to enable or disable the conversion (i.e. if you want a positive or negative number). Use a word generator to supply the two 4-bit inputs. Use hex displays on the inputs and output. Use a probe on the carry output and add/subtract control input. Use a 74LS283N Adder chip and a 74LS86N XOR chip. Simulate the circuit in Multisim and test enough input combinations that you are sure the circuit is working properly. Make sure you test in all theranges of numbers that are possible. List the numbers tested (input and output) below. Print out your circuit and attach.
What is the possible range of inputs for addition?
What is the possible range of inputs for subtraction?
What is the possible range of outputs for addition (including carry out bit)?
What is the possible range of outputs for subtraction (including carry out bit)?
The feedback system for the Buck circuit can be analyzed by separating DC component from small signal perturbation. The performance of the feedback can be assessed by examining the Bode plot of the loop transfer function GL(s).
The bottom of the conduction band at one end of a silicon resistor is at the same energy level as the top of the valence band at the other end. What current flows through the resistor if the resistance is 1.12 kOhms

A synchronous generator rated 1350 MVA at 0.9 pf, 22.5-kV, Xs=11.6% is connected to a power system through a 1500 MVA, 7.9% 24-kV/230-kV generator step up transformer. The power is generated into a 230-kV system.
the solutions at both frequencies about a total transit time of 1000 years (speed of light in a vacuum result) such that subtracting one from the other leaves just the delay that is of order of 1 second.
In a certain n-type region of a semiconductor in thermal equilibrium, there is a hole concentration with the following spatial distribution: po(x)=103(1 9×103x)cm 3 for0 x 10 4 withxincm Assume that in this region, the electron mobility and hole mob..
Phase current - Neutral Grounded Assume that the load is star connected with the neutral grounded. Each phase has a series RL load with R = 5 ohms and L = 20 mH. Calculate and plot the Phase a current Ia using Fourier techniques.
determine whether the statements are valid or invalid. If a statement is valid, please give a proof as in problem 1. If a statement is invalid, you need only provide a counterexample. If x + y = x + z, then y = z
