Band pass filter

  1. Jan 4, 2009 #1
    1. The problem statement, all variables and given/known data

    draw a circuit for a and pass filter using only capacitor and resistors that will transmit signals in the range 200-1500 hertz. if there are only 100 nf capacitors choose resistor values.

    2. Relevant equations



    3. The attempt at a solution

    i know the circut would look like this http://www.web-books.com/eLibrary/Engineering/Circuits/AC/02121.png
    but am not sure how to work out r.
    thanks

    What you have there is a low pass filter in series with a high pass filter, thus creating a filter which will only allow a range of frequencies through.

    HINT:

    In order to allow the range 200Hz -1500Hz to pass what must be:

    The cutoff frequency for the high pass filter?

    The cutoff frequency for the low pass?

    Can you use this information to find the resistor values?
