    Hey Guys,

    Have a look at the following schematic and please let me know how the capacitor values are assigned to get the correct frequency levels i.e. 100Hz, 300Hz, 1kHz, 3kHz, 10kHz. If I'm wanting to change these frequency levels how would I do the calculations?

    Thanks

    The formula for calculating the parts for different frequencies and different Q's is in the datasheet by Rohm.

    You should never make anything without looking at the datasheet.
    I get my free datasheets from www.datasheetarchive.com .

    Ok, thanks. I'm wondering for this circuit should I use AC or DC?

    Thanks
