    Hello all
    i am a masters student facing a rather difficult problem
    Is it possible to design a 2nd order butterworth BPF ?
    i mean the mid freq. and the BW are givens , yet he wants a butterworth filter
    doesnt butter worth already specify the Q:quality factor for me!?
    how do i set the BW, then
    i think that it is impossible to be done unless its a 4rth order!

    the question wanted to use the salen key configuration but i am open to suggestions.

    Thanks in advance
