1. Consider this argument: “We should continue to resist the calls to change the NFL franchise Washington Redskins’ team name. Recognized that other professional sports franchises have names that are equally insensitive and/or offensive. For example, the Pittsburgh Pirates are effectively celebrating a group of people who each year take hundreds of innocent people hostages and often steal commercial property. And yet there is no push to change the names of these other sports franchise.” what is the secondary analogue of this argument?

A: the Washington redskins team name

B: the insensitivity and/or defensiveness of the Washington redskins team name

2. Evaluate the following argument: “if one must listen to music from Fleetwood Mac, then one should listen to the early years of their music. Its false that one must listen to music from Fleetwood mac. Hence one should not listen to the early years of their music.

A: Deductive--invalid
B: inductive-non-cogent

3. which describes this text better:” one ought not disparage classical music. that is, of course, unless he or she desires to be seen as an ogre.”

A: Argument

B: Description

4. evaluate the following argument: “you must choose either to foster a literary mind or mathematical mind. you have chosen to foster a mathematical mind. so, you must have chosen not to foster a literary mind.

A: Deductive-invalid

B: Deductive-valid and unsound

C: inductive-cogent

5. Identify the fallacy of this argument: “The integrity of smith’s research requires special scrutiny. Smith has twice in the past been found guilty of plagiarizing findings and means of presentations that other researchers have published.

A: slippery slope

B:no fallacy

6. Consider this argument: “We should continue to resist the calls to change the NFL franchise Washington Redskins’ team name. Recognized that other professional sports franchises have names that are equally insensitive and/or offensive. For example, the Pittsburgh Pirates are effectively celebrating a group of people who each year take hundreds of innocent people hostages and often steal commercial property. And yet there is no push to change the names of these other sports franchise.” what is the primary analogue of this argument?

The Pittsburgh pirates team name

B: the insensitivity and/or offensiveness of the Pittsburgh pirates team name

7. Evaluate the following argument: “if Butch is a legal driver, then Butch is at least 16 years of age. Butch is at least 16 years of age. Hence, Butch must be a legal driver.

A: deductive-invalid

B: inductive-cogent

Explain the basic operation of an operation amplifier. What are the most significant characteristics of such a device and in designing a circuit what parameters of the device must be considered?

This assignment should challenge the students to research and identify a real-world problem as well as come up with a concept for a potential solution. The identified problem should be corroborated with at least 3 reputable sources. The proposed solution does not need to be fully formulated but the students should reasonably demonstrate that the feasibility of completing a prototype during the timeframe of the course with available resources.

A brief theory about Transmission Lines. (Only text. 3 paragraphs maximum)

1. With regards to electrical noise and inductive coupling, explain the purpose of running current carrying conductors in their own raceway separate from signaling cables.  Does the type of raceway material, ferrous vs non-ferrous make difference?

3. List two materials commonly used in TVSS (Transient Voltage Surge Suppressors).  As well,

UL 1449 uses 3 categories when rating Surge Protective Devices (SPD) / Transient Voltage Surge Suppressors (TVSS).  List the categories and explain how they apply to a TVSS’s performance.

A brief theory (3 paragraphs minimum) about Transmission Lines.

Describe briefly how the laser is modulated? Using the simple rate equation for carrier and photon density, explain why the high-speed small-signal response will behavior like L-C circuit? Why the bandwidth (resonant frequency) increases as the current increases?

(e) In the steady state and above threshold, why will the gain and carrier density inside a semiconductor laser be clamped (limited)to the threshold condition? How about photon density inside the cavity? If the driving current is time varying form, are gain and carrier density still kept in constant values? How about in AC driving conditions?

A physical voltage m(t) between a pair of wires modulates a carrier c(t) for transmission as s(t). The system is DSB-PC AM. Part of the message’s spectrum is M(f) = 0.6*exp(j*20)*delta(f-96) + 0.4*exp(j*45)*delta(f-104)+...

But this is not the whole spectrum, for if it were the whole spectrum, then m(t) would be complex, whereas physical voltages cannot be complex

given:

a) Write the whole spectrum M(f). Also, plot |M(f)| and arg M(f).

b) Suppose that the carrier frequency is fc = 800 and that the deviation constant is k = 0.4. Plot |S(f)| and arg S(f). Show your supporting work.

c) your solution included both sidebands of S(f). However, are both sidebands of S(f) really required?

d) why can S(f) omit a sideband even though M(f) cannot? [Hint: like m(t), s(t) too is constrained to be real valued. Explain however why omitting a sideband does not make s(t) complex.]

i) What is the general expression for the electrical resistivity of a metallic material with eutectic composition such as the Pb-Sn solder material? Identify all the parameters in the expression.

ii) Based on your knowledge of single phased and multi-phased materials, explain how you can make material choice for a device based on resistive heating such as stove heating coils. Indicate how the enhancements of the heating efficiency can be achieved in single phased and multi-phased materials.

Write down the overall general expression for the conductivity of a material taking into consideration the different types of charge carriers. Identify all the parameters in the expression:
