DIY Low Pass and Mid/High Pass (Bass Blocking) Filters

runslikealpaca · 17th June 2009, 08:40 PM

Hey guys, I am trying to build two filters passive filters, as stated above, a low pass one and one that blocks all the lows and allows the mids and highs through.

I really have no idea where to begin, I remember in my electronics class that it had something to do with LR circuits for the low pass and an RC circuit for the high/midpass.

I would like specs to be:
Low Pass: 20-120 Hz
Low Blocking (High/Mid Pass): 120-20k Hz

I am building these two filters to filter two input signals... the filter is between the iPod (for example) and the amp.

Any help would be greatly appreciated!

Thanks everyone
