Hi guys,
Im looking at doing a design that will have a cut off frequency of around 2-3Khz with a fast attenuation rate, the components need to be passive and it also needs to block DC. Ive tried a LC filter (4mH with 3.5uF) with a DC blocking cap in series but the attenuation rate it quite slow. Any ideas?
