    I want to make an AC power filter for my audio system and I came across

    The scheme is legible in any language

    Could someone please tell me how the designer came up with the element values used. I would like to know how to calculate the cutoff frequency, which frequencies are attenuated and which are free to pass, and everything that you can think of.

    Please help
