> Intelligent Roaming
> Location-Aware Computing
> Proactive Health
> UPnP* Technology
Send me a paragraph summary email of what you found looking into the future!
10/2/2003 Read Ch. 2 from p. 33- 45. Bring book & calculator to class. VAB audio labs on Thursday, 1:30 -3:05 pm.
10/3/2003 Read p. 46-53 in the book. We'll work on Audio VAB's again on Friday.  
10/8/2003 Read p. 55- 58. Do Exercises 2.2 #1-14 Do these Exercises on paper, in Word, or in Excel. Email to me if electronic.
10/10/2003 Ch. 2 VAB's #2.1-2.7 done by end of Thursday Please visit the Ch. 2 VAB page to see the complete list of VAB's and what you are expected to work on this week.
10/9/2003 Read p. 59- 69. Be able to plot and manipulate sinusoids on your TI-83 calculator on Thursday.
Be able to use radians to graph sinusoid equations and predict the outcomes based on the concepts in the reading.

You'll need to memorize the sinusoid basic formula and explain it:

s(t) = A cos ((2pi*f)t) + phi where phi is the phase shift or delay/gain in time of the sinusoid.

10/21/2003 Read the "Clock" handout. Do Review Questions 1-12 at the back of packet. Be sure to know the items in the article's Glossary.

Email answers or bring in a hard copy.

10/22/2003 On the "Clock" handout, answer Exercises #1-4,6, 10,12,13. Need hard copy in class

10/28/2003 Read "Radio" packet. Know vocab in packet.  
10/29/2003 "Radio" packet questions Please answer the following in full sentences. Email answers to Mr. R.
  1. What, in general, causes radio waves to be generated?
  2. What, in general, generates periodic signals? What is the best way such signals can be mathematically represented?
  3. What is resonance? Does it relate to “harmonic oscillation”? How does it apply to sending and receiving radio (or any Electromagnetic or EM wave signals)? Give an example.
  4. What factors limit the type of signal that can be generated by electrical circuits. Look at a) frequency, and b) strength of the signal.
  5. What is a polarized EM signal? How does changing the orientation of the radio to alter the quality of reception illustrate this?
  6. Describe how AM radio signals transmit voice data. Why is it of a lower quality (has a lower SNR) than FM?
  7. Describe how FM radio signals transmit voice data.
  8. What part of the general sinusoid equation must the receiver alter in order to generate the effect of stereo? Please be specific.
10/30/2003 Read "Tank circuits" 2 page handout & answer these questions Email these to Mr.R:
  1. What is a tank circuit? What is it useful for?
  2. Deduce the function of a capacitor from the illustration on the left margin of the page. Hint: In the "sloshing" analogy, what role does the capacitor play?
  3. What is an inductor? What is it used for?
  4. If you want to increase the resonant frequency or inherent beat pattern of the tank circuit (say from KHz to MHz), what should you do to the capacitor and inductor: make them larger or smaller? Why?
10/31/2003 "Tooth Tunes" description emailed
Email your description of how the radio and "Tooth Tunes" device worked. Start your essay with the output jack of the radio. Include in your essay these terms: radio signal, antenna, tank circuit, electrical signal, voltage, fluctuations, copper coil of "tooth tunes", electromagnetic field, permanent magnetic field, induction, attraction, repulsion, compression, frequency, treble, bass, resonant energy transfer, outer, middle, and inner ear, nerves, brain.
