North South University ETE 321 – Spring 2010 Instructor: Nahid Rahman Assignment #1 Total Marks: 100 Worth: 7.5% 1. Consider the sinusoidally modulated DSB LC signal shown below. The carrier DSB-LC frequency is ωc and the message signal frequency is ωm. (a) Determine the modulation index m. Solution: Amax = 25 Amin = 5 − 25 − 5 = = 0.67 + 25 + 5 (b) Write an expression for the modulated signal φ(t). Solution: 1 1 ) = (25 − 5) = 10 = ( − 2 2 1 1 ) = (25 + 5) = 15 = ( + 2 2 = + cos = cos

BKM CHAPTER 5 1. The Fisher equation tells us that the real interest rate approximately equals the nominal rate minus the inflation rate. Suppose the (expected or realized) inflation rate increases from 3% to 5%. Does the Fisher equation imply that this increase will result in a fall in the real rate of interest? Explain. The Fisher equation relates nominal rates required by investors to real rates required by investors and inflation. You can think about this from two perspectives: i. Ex-ante

Discuss the cause of the Tacoma bridge disaster‚ in terms of waves‚ vibrations‚ and resonance. Elaborate the effects with relevant equations and formulae. The Tacoma bridge collapse can be attributed to the waves caused by the buildup of energetic vibrations. These energetic vibrations were built up from the bridge “taking energy from the steadily blowing wind” (Crowell). Eventually enough of these energetic vibrations built up to cause resonance within the system‚ causing the wave-like motion

1 Describe the graphical coordinate system in Java. Where is the origin? What units apply to the x‚y coordinates? Java AWT Graphic component is different with respect to x and y coordinate that we have learnt in math. It defines its own coordinate system to specify where and how drawing operation will take place. Here the origin (0‚0) is at the top left corner of the component. Here X coordinate increases as we move right and Y coordinate increases as we move down. . The units for X and Y is in
