1. Open m file of sampandquant, uniquan and Prelab4 in MATLAB.

a. Set the quantization levels of PCM (L) as 2 and 32. Compare your results.

b. Why did we choose the cut-off frequency of the ideal LPF as 30 Hz. What happens for small or very big values of the cut-off frequency?

c. Change the message signal as : xsig = cos(2pit) + cos(2pit)

d. First set the quantization levels of PCM (L) as 2 and 32. Compare your results. Then, set different values of L and compare your results.

e. What should be the cut off frequency of the ideal low pass filter for the signal given in part (c) so that the original and the recovered signals will look like each other?

Assume that A and B are MATLAB arrays with 10 rows and an equal number of columns (the number of columns is not given). Important: Next, the expression "a single line of code" implies a single command or equality. In other words, the code:

X=A+1; X=X+B; is considered to be TWO lines of code, even though it can be written as one line.

(a) (3%) Write a single line of code which saves the first two rows of array A as a new array X.

(b) (4%) Write a single line of code which replaces rows 4 and 5 of array A with rows 2 and 6 of array B.

(c) (3%) Write a single line of code which divides all elements in array A by the corresponding elements in array B and saves the resulted array as X.

(d) (4%) Write a single line of code which adds the transpose of array A to array B and saves the result in array X. What should the number of columns of A and B be so that this operation does not result in an error?

(e) (4%) Write a single line of code which uses the MATLAB function "sum()" to find the sum of each row

(f) (3%) Lets call N the unknown number of columns of arrays A and B. What is the size of array X = [A B]; ?

(g) (3%) Again, N is the number of columns of arrays A and B. What is the size of array X = [A;B]; ?

(h) (3%) Assume that the arrays A and B have more than 5 columns. Write a single line of code that divides all elements in A by the B element located at row 3 and column 4.

(i) (5%) Write a single line of code using the MATLAB function "find()" which finds the location of all elements in A which are greater than 1. Then, write another line of code which replaces all these elements in A by the number 2.

Explain how the clamping circuit adds or subtracts a DC component to an input voltage.

1) Explain the operation of the Safety (Light) Curtain.

2) Explain the role of 'three safety zones' in robot work cells?

3) In your opinion, what is the difference between safety and security?

Identify the signals used in broadcasting TV studio? Discuss about the signals which are combined in fewer parts for transmitting channels in TV broadcasting.

Electric Drive Problem

4) How is torque related to the power rating of each of the motors? If an actual physical motor with the same specifications as the above PSIM model s is available in the lab and this experiment was actually performed in the lab, what should be the minimum current rating of the DC power source for each motor ? You may want to do an online search on this for a deeper insight into this concept

Case Study: Engineering Ethics in a Technology Startup

Introduction

A business’s reputation and brand name depend upon the behavior and values of that
business. Businesses should be socially responsive, fair and just, with a positive
reputation for business conduct. Engineering entrepreneurs must confront ethical
challenges such as engineering design reliability and salespeople’s ethical standards.
Ethical decisions in sales include: intentionally misrepresenting a faulty product,
economic tradeoffs, short-term v. long-term gain. In general, a company’s beliefs and
values matter, along with business conduct and the representation of facts to customers
and investors.
This case study attempts to identify the specific ethical issues and obligations of an
entrepreneur and his employees in making decisions for his startup company.
The Case
Tina is a new hire at a startup company that produces very expensive security cameras
primarily for large organizations. Tina is hired to engineer and troubleshoot
malfunctioning cameras.
One day, one of its Fortune 500 customers reported to Tina that a number of the cameras
out of its last big shipment were not functioning properly. The customer also informed
Tina that the serial and revision numbers on these units were different from the rest of the
units.
Tina’s technicians inspected the cameras. Based on the results of their inspection, Tina
realized that her company sold units that were from a bad batch. Tina wanted to tell the
customer why the units failed but recognized that if she disclosed this information, the
customer would be eligible to receive replacement units at no additional cost. On the
other hand, if she blamed the failing units on something else, such as improper care, her
company would be able to charge the customer for replacement units.

As a recent hire, Tina decided to discuss the case with David, the owner of the startup.
David told her that she should minimize his company’s losses. Tina is concerned with her
job security. But she also wanted to be honest with this major customer.

Questions:
1. What are the ethical issues in this case?
2. Who are the actors and what is their obligation in this case?
3. Would the issue in the case have occurred if the actors followed the IEEE code of
ethics (https://www.ieee.org/about/corporate/governance/p7-8.html)?
4. What sections of the IEEE code of ethics would have been relevant in this case?
5. Should Tina’s personal beliefs play a role in this case? What about the personal beliefs
of David?
6. What should Tina do? Does she have a moral obligation to obey or disobey the owner?
Why?

What are the characteristics of the EMG? Bandwidth (frequency content)? Magnitude (amplitude)? How will determining the bandwidth guide your filter design? How will determining the amplitude guide your amplifier design? Using these criteria and support information, roughly design an amplifier (provide a circuit schematic) to accomplish these tasks. What will be the gain of your amplifier, what type of filter do you need, what are the cut off frequencies?
