Imagine a situation that you are on an island in the middle of a sea . The island is of around 10km long and put one transmitting antenna at one end of the island and another receiving antenna at the other island. The island has no man-made infrastructure but has trees, plants and animals. List the types of attenuation that the transmission signals will suffer and explain why?

Expert Solution

Attenuation: The impairment is caused by the strength of signals that degrades with distance over a transmission link. Three factors are related to the attenuation:

•The received signal should have sufficient strength to be intelligently interpreted by a receiver. An amplifier or a repeater is needed to boost the strength of the signal.

•A signal should be maintained at a level higher than the noise so that error will not be generated. Again, an amplifier or a repeater can be used.

•Attenuation is an increasing function of frequency, with more attenuation at a higher frequency than at lower frequency. An equalizer can smooth out the effect of attenuation across frequency bands, and an amplifier can amplify high frequencies more than low frequencies.

Noise

Additional noise on N/Ws (networks) such as RFs (radio frequencies), leakage in wires, electrical currents can interfere by the signal to cause this. If the noise is more, then this will be more.

Travel Distance

When the transmission in a cable travels for long distances like from source (current place) to destination (connection supplier), then it experiences more noise while travelling.

Physical Environs

Physical environs which include installation of improper wiring, wall barriers, the temperature can alter the transmission, then attenuation can be caused.

Transmission Medium

An electromagnetic field can occur around the transmission once all the signals broadcasted down, then energy losses will occur in the downside of the cable based on the length & frequency of the cable.

Environmental

This kind of attenuation relates to loss of signal power because of the transmission medium, whether that can be connected to copper wire, fiber optic or wireless.

In an attempt to escape his island, Gilligan builds a raft and sets to sea. The wind shifts a great deal during the day, and he is blown along the following straight lines: 2.5 km 45° north of west; then 4.70 km 60° south of east; then 5.1 km straight east; then 7.2 km 55° south of west; and finally 2.8 km 10° north of east. What is his final position relative to the island? ______ km ______ ° south...

Imagine you have two beakers: one with 750 ml of sea water and one with 750 ml of distilled water. You bubble CO2 into each and take the pH of each solution every minute for 15 minutes. Q1: Why did pH decrease when CO2 was added to water and sea water? Q2: Why did the pH of the water decrease more quickly than the sea water? Explain how the buffer system in our blood is related to ocean acidification. According...

1. Imagine that you model your lungs as a 5 L sealed balloon at sea level: How would the pressure and temperature at 100 m below sea level affect the speed of the air molecules in your lungs compared to their speed at sea level? Assume that the temperature of your body will adjust to the surrounding temperature as you descend. Keep in mind that, in general, your breathing adjusts to keep the same number of particles of air in...

Suppose a rising sea level leads to the splitting of one Pacific island into two smaller islands. A population of geckos on this island is thus split into two small populations. An evolutionary biologist interested in studying the effect of this split performs an analysis of a polymorphic single nucleotide located in an intron of the alpha-tubulin gene. Immediately after the split, the two populations start at different frequencies for a 'T' allele. Population 1 has a frequency of the...

Imagine a situation where a neighbor has an ugly tree that you would like to remove. You complain but your neighbor likes her tree. Now suppose that she has the legal right to keep it; then, according to the economist Ronald Coase’s analysis, you would have to pay her to remove it. (Case 3 & 4 below) If you have a right to protection from her pernicious tree, then she can pay you to tolerate it. (Case 1 & 2...

Solow Growth Model: Suppose a fictional island called San Bruno in the Mediterranean Sea has a production function of Y=F(K,L)=K0.5L0.5. Note that capital per worker is k=K/L and output per worker is y=Y/L. Suppose there is no population growth and no technological improvements in San Bruno. Assume initially L=100 and K=6400. Also assume that the savings rate in this economy is 24%. There is not international trade and no government taxes or spending. Therefore, Investment equals Savings. I=sY. On a per worker...

Imagine an island with many people on it, each of whom can catch some number of fish or pick some number of coconuts (each person's numbers being different from the rest). Now imagine that they discover a new invention--the ladder! The ladder allows every person to pick twice as many coconuts as before. a. What happens to the marginal cost of fish for each person and what happens to the marginal cost of coconuts? b. Sketch the PPF and show...
