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

You might be able to find a 7000Hz ceramic filter that would give you a very narrow bandpass.
I'll work with my engineering software to see if I can come up with an IC-based filter that might work for you.
Please email me so that we can communicate.
I'll work on a filter design and email my results to you.
