1. The problem statement, all variables and given/known data I noticed that bandwidth is the difference between the frequencies that gives half power: But sometimes it is the difference between when the frequency is 0 and the frequency that gives half power: So the definition in my lecture slides states that bandwidth is the difference between the upper and lower bounds of the passband where passband is the range of frequencies with nearly constant gain. So does that mean frequencies past the bandwidth will be filtered out by the network? But if you look at the graphs there is still a gain when you are at frequencies out of the bandwidth range. What does bandwidth really mean?
