    Hi members,
    I am doing an audio amplifier and I need a low pass and a high pass filter to block unwanted signals. In simpler words what I want is a bandpass filter, but I know how to do a low pass and high pass only one tackling them as an individual and not when I need to use them together as my knowledge I have, thats what I imagine that would need to happen. Is there any good tutorial on how to this for an inverting amplifier please as shown in the below link.

    Thanks in advance.

    Regards

    An easy way to design active filters is the free Filterpro program from TI.

    Thanks for your help, but what I need is to work it from first principles. I know how to work out the capacitors and resistors needed for a high pass filter and for a low pass filter, my only problem is how do I configure both at once it to have a bandpass filter. Thanks again.
