Important information about Noise
Explain the role of the central limit theorem in the behavior of Additive White Gaussian Noise (AWGN).
Why is noise referred to as Gaussian?
What is meant by white and why is thermal noise white?
Describe in you own words how a modem works and what steps the data goes through to be sent from one terminal to another via modem.
What are the respective advantages and disadvantages of the asynchronous and synchronous communication modes from a reliability perspective?
Analysing an RF splitter and power levels, A splitter is a device that has a single input and several outputs. It is used to send a signal to several different locations
In order to eliminate the cost of calling cards, the company in the above problem is considering a new policy that requires blocked callers to redial over and over until they get a trunk.
A baseband sine wave signal with frequency 4.0 kHz is modulated onto a carrier at 1.050 MHz using DSB-LC AM. What are the frequencies of the sidebands of the RF signal?
Why developing software for wireless devices is challenging? List and briefly describe the two (2) reasons given in your textbook for why developing software for wireless devices is challenging.
Spectrum Analyzer, A spectrum analyzer is connected to an unknown signal. The spectrum analyzer displays the power level of signals in dBm vertically and frequency horizontally. The spectrum of the unknown signal creates the following display:
