Relationships Between Symbol Rates and Bandwidths
Consider a variation of 5 with a QAM communication system that employs raised cosine pulse shaping at the transmitter and a carrier frequency of 3GHz. In this you will answer various questions about the relationships between symbol rates and bandwidths.
Suppose that the symbol rate is 1 mega symbol per second and that the raised cosine has 50% excess bandwidth. What is the baseband absolute bandwidth?
Suppose that the symbol rate is 1 mega symbol per second and that the raised cosine has 50% excess bandwidth. What is the passband absolute bandwidth?
Suppose that the absolute bandwidth of a signal is 1MHz at baseband. What is the maximum symbol rate that can be achieved with a raised cosine pulse?
Suppose that you have a raised cosine pulse shape with absolute bandwidth of 2MHz at baseband and excess bandwidth of 50%. What is the symbol rate?
Suppose that the absolute bandwidth of your modulated signal is 3MHz at baseband with an excess bandwidth of 25%. What is the Nyquist rate? What is the sampling rate at the receiver?

40-38 points
More depth/detail for the background and significance is needed, or the research detail is not clear. No search history information is provided.
83-76 points
Review of relevant theoretical literature is evident, but there is little integration of studies into concepts related to problem. Review is partially focused and organized. Supporting and opposing research are included. Summary of information presented is included. Conclusion may not contain a biblical integration.
52-49 points
Content is somewhat organized, but no structure is apparent. The use of font, color, graphics, effects, etc. is occasionally detracting to the presentation content. Length requirements may not be met.
