Stereo bandpass filter

billman · 9th November 2010, 04:32 PM

Hi,

I am trying to tune my car and made an adapter cable from the factory knock sensor to a small stereo jack.

I sounds good but i would like to interfere a bandpass filter so i only hear the frequency i am interested in (in this example 6900-7200 Hz).

Can someone help me out here since circuit design is not my field? :-)

I would not mind if it would also amplify the signal and gave me earphone output. (if there is a ready cheap solution, let me know).

thanks
