What are some typical applications for stepper motors and what do engineers do to make sure the rotating shaft is at a particular position even though it is operated in an open-loop system?

Given the complementary solution and the differential equation, Give the particular and the total solution for the initial conditions.

Use C1 and C2 for the weights, where C1 is associated with the root with smaller magnitude. If the roots are complex, the complementary solution is the weighted sum of complex conjugate exponentials, which can be written as a constant times a decaying exponential times a cosine with phase. Use C1 for the constant and Phi for the phase. (Note: Some equations in the text give the constant multiplying the decaying exponential as 2C1. This was done for the derivation. The constant for this problem should be C1 alone.)

(basically anything with a sin function will be marked as wrong by me)

y(0)=7 y'(0)=2   

Given the differential equation y′′+8y′+25y=2cos(1t+1.0472)u(t).

Complementary:(e^(-4*t)*(C1*cos(3*t+Phi)))*u(t)

1. A house has following information on bulb fixtures (Table I). The owner of the house wanted to replace all the bulbs fixtures with CFL type. The efficiency information of a typical CFL is given in the Table II and the required CFL light output (in lumens) for each of the replaced bulbs is given in Table I.  

                        Table I: Bulb fixtures information

The bare bulbs and reflector type bulbs are being used for 8 hours and 6 hours respectively every day.    

                      Table II: Efficiency recommendation information

The house owner requires answers for questions 1 to 4 before he/she takes a decision.

1. Using the information given in Question 1, calculate the total annual energy consumption cost for the original fixtures if cost of energy per kWh is $0.08. (1 point)

1. $326
2. $510
3. $894
4. $900

2. Using the information given in Question 1, what is the difference in the annual energy consumption if all of the given bulb fixtures are replaced by typical CFL? The required CFL light output for the replaced bulbs is given in Table I and the CFL bulbs are used the same number of hours as replaced bulb types. (2 points)

1. 1240 kWh
2. 2840 kWh
3. 2926 kWh

1. Create a 4-bit Register
2. 1. This is very similar to your flip-flop design from lab task 1. Ensure that your 4-bit register has inputs “D” (dat, “CLK” (the clock), and “RST” (an asynchronous reset), and an output “Q”.
3. 2. [3 pts] Create a test bench and ensure that your 4-bit register operates correctly (test your reset signal and ensure that you can store a couple different values in the register). If your output behavior is correct, then copy your VHDL design code and simulation screenshot below:
4. 1. Place your 4-bit register’s VHDL design module code here (copy-paste as text, not an image):
5. 2. Place a screenshot of your simulation here (enlarge your waveform and do not crop the image (it should show the whole screen) or you will lose points):
6. 3. Explain why your circuit is (or is not) working correctly:

(a)Discuss the classification of logic families and their characteristic parameters.
(b) Design q mod -6 unit distance code counter using D flip flop.
