Bandpass Filter component calculations.

AI Thread Summary
Calculating components for a bandpass filter involves understanding it as a combination of low-pass and high-pass filters. The distance between poles and zeros affects the calculation complexity, with wider separation simplifying the process. To derive the component values, one may need to use transfer function equations if the poles are not sufficiently apart. Clarification on the term "poles" is also sought, indicating a need for foundational knowledge in filter design. Understanding these concepts is essential for accurate bandpass filter calculations.

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.
Thanks

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.
