Active Second-order low-pass Butterworth filter

  1. Apr 13, 2005 #1
    I need help in designing an active 2nd order low-pass Butterworth Filter that meets certain requirements.
    The requiremetns are that it needs to be a minimum 2nd order coincident pole system design with a break frequency at 6kHz
    and a minimum 40dB roll-off at the break frequency.

    I am no expert on filter design, but I may have some helpful suggestions and there are others here who can assist you.
    What have you done so far in your design? At what point are you getting stuck?
