CRISespecialist -> Thanks for the tip. That's what I've been doing with my first design (the one I made a month ago), and it worked out
ok, but I had to modify it again...
Audioguru -> That's the problem. If I want to increase that resistor's value, I'll have to increase the other ones as well (in the order of
mega).
JimB -> I've looked more into the stuff you told me about. The problem with cascading a low-pass with a high-pass filter is that it won't
work for a hiqh-Q factor (mine has to be 80). The book suggested that I should use the bandpass filter shown in Fig 5.16. I did
some more research into that design and it turns out that in order to have one thing (High-Q factor), you have to give up another (a gain
of 1 at the desired center frequency), meaning that I cannot change them independently.
For now, I'm thinking of using the LC filter I designed last semester. I'll try and add an op-amp to it to see what kind of results I get.
