Density Ratio

Question

A digital communication system uses continuous-phase FSK with modulation size M = 8. The center frequency is fc = 500 MHz, the bitrate is Rb = 30 Mbps, the received signal power is S = 6 nW, and the channel is AWGN with double-sided power spectral density N0/2 = 2 ∙ 10-21 W.

1) What are the instantaneous frequencies to be used for each symbol, in order to minimize the required transmission bandwidth, and what is then the value of such bandwidth? How much is the resulting spectral efficiency?

2) What is the value of the bit energy to noise density ratio?

Question

In a Word document,  explain your cause and effect topic.  Describe the approach you will take (effect to cause, cause to effects, cause to chain of effects, etc.). See the directions for more resources (videos) and see your text book for sample essays.  Topics we will not engage include the following:

Obesity, violent video games, poverty, racism, school uniforms, sexism, depression, sex education, drugs/drug abuse, global warming, domestic violence/child abuse, alcoholism, death penalty, euthanasia, abortion, police brutality, capital punishment.

Try to avoid Internet “topic lists” and come up with one of your own. Brainstorm with a classmate. Avoid obvious and predictable effects. This list is not comprehensive.
