I got an input signal 20Hz - 20KHz. I would like to split it into 2 ranges 20Hz - 3KHz & 3KHz - 20KHz (for example). I am going to process each signal differently and add them together afterwards (via a summing amplifier?). My question is how can I calc. the filters needed for the splitting so that the signals will overlap just a bit and when glued together won't create a huge peak in the overlapping range? -60dB is about as much as I wish to cut.
