    I found a design on the internet and i want to make a circuit from this design but i don't understand about it, such as how to calculate some values: center frequencys, resistor.... I want to understand about because if have some problem i can repair and calculate again some value!
    Does anyone help me calculate this circuit!! Thank you very much

    Welcome to the forum.
    The calculations would be quite extensive. I suggest you download (free) the LTspice simulator from Linear Technology and run a simulation of the circuit. That will enable you to try different component values and study their effect. Let LTspice do the calculations for you! ;)

    It couples AC signals from IC1 output to the filter network.
