T tresca Member May 2, 2009 #1 Might seem a silly question but after thinking about I really don't know the answer. In order to create a bandpass filter, we need a HPF and a LPF cascaded. Lets say you are trying to make a 5th order BPF. How does that work ? Is each filter type(HP or LP) 5th order, so therefore, 6 opamps total ? Basically, how can i make a 5th or 6th or 7th order bpf ? (i dont need schematics or formulas)
