60Hz filter?
« on: September 03, 2008, 10:56:13 AM »
I design an signal amplifier, but it seems that i have interfierence with the supply voltage transformer. I can tell because the sound is low frequency.
I want to design a filter for these frequencies, to cutoff 65 Hz and bellow. Any suggestions?

Thank you qwerty

You should check the Electronic circuits archive for a filter. You will find one.
