1. Lecture 4 review What prevents us from sending data at infinite speed?
Define bandwidth and capacity?
What is symbol?
Define baud rate and bit rate, what is their relationship?
What is the relationship between the number of bits per symbol and the number of symbols used in a communication system?
Among the three variables: baud rate, bit rate, the number of symbols used, which one does bandwidth directly affect? Which one does noise directly affect?
Nyquist’s theorem
Shannon’s theorem
Explain maximum likelihood detection
