about Band-PassMultiple Feedback
i want to know why i need to connect dc reference with two resistor in series instead of directly to the positive pinattached picture that explain ?thanks
These two resistors provide positive feedback to increase your Q. If you don't use these resistors, the Q of your circuit will be lower and you won't get as sharp a transition from passband to stopband. The filter wizard typically adds these resistors when your Q is higher. If you have a bandpass circuit with smaller Q's, you probably won't see these.
