Homework Help: Bandpass Filter component calculations.

  1. Jun 25, 2009 #1
    Once again I'm going through all my old homework and taking the notes I should have done in the past, and I am stuck on calculating the components on a Bandpass filter. How would I go about this. I have the answers I just want to know how to find them.

    That's sort of a cascaded LPF + HPF, right? If the pole and zero are pretty far apart, that makes the values easier to calculate (Quiz Question -- why?). How close are the poles in this question? Can you use the approximation? If not what equation do you need to write (hint -- something about a transfer function)?

    Yes bandpass filters are Low pass and High pass filters in series. As to the quiz question, I have heard the term poles used many times, but have no clue as what they refer to.
