1. Discuss the phenomenon of dispersion.
2. Discuss the concept of group velocity with the aid of an example.
3. What is a dispersion diagram? Explain how the phase and group velocities can be determined from a dispersion diagram.
4. When is it meaningful to attribute a group velocity to a signal comprised of more than two frequencies? Why?
5. Discuss the propagation of a narrow-band amplitude modulated signal in a dispersive channel.
You construct a price-weighted index of 55 stocks. At the beginning of the day the index is 8,710.44. During the day, 54 stock prices remain the same, and one stock price increases $5.40. At the end of the day, your index value is 8,757.89. What is t..
Compute the price of a 5.6% coupon bond with 18 years left to maturity and a market interest rate of 5.9%. (Assume interest payments are paid semi-annual and the face value is $1000.) Is this a discount or premium bond?
Read the requirements for each problem and plan your responses carefully. Although your responses should be concise, ensure that you answer each of the required components as completely as possible. If supporting calculations are required, present th..
The universe of the narrator's characters in Breakfast of Champions is apparently his attempt at writing about life; the universe which includes the narrator himself as a character can be seen as Vonnegut's attempt at the same
Sawchuck Consulting has been profitable for the last 5 years, but it has never paid a dividend. Management has indicated that it plans to pay a $0.25 dividend 3 years from today, then to increase it at a relatively rapid rate for 2 years, and then to..

You want to accumulate $3 millions by your retirement date, which is 25 years from now. You will make 25 deposits in your bank, with the first occurring today. The bank pays 7.82% interest, compounded annually. How much must your first deposit be to ..
Find an equation of the tangent plane to the surface z = ex^2-y^2, at the point(1, -1, 1). Determine whether the function is a solution of Laplaces equation uxx uyy =0. u= ln(x2 - y2) + 2 tan-l(y/x).
Thomson Media is considering some new equipment whose data are shown below. The equipment would be depreciated over a 3 year MACRS life, but it would have a salvage value at the end of Year 3, when the project would be closed down.
