Hi everyone, Need some help with this problem. I need to design a low-pass active filter circuit such that its roll off attenuates frequency components at 14kHz or more by more than 17dB, Also it is desired to have the passband gain positive that doesnot deviate from 40dB by more than 3dB, The passband frequency needed is 280Hz and below.
Hope that someone can help me ASAP . Thanks.....
Get Don Lancaster's "Active Filter Cookbook."

Thanks a lot John will try to get hold of the book....appreciate that
If you have an RC filter where 280*2*PI=1/RC, what will the amplitude of a
14kHz sine wave be when passed through it? How about after you amplify it by 100?BTW, questions like this are often better received over on the sci.electronics.basics newsgroup.
