band pass filter

[Weed]

Hi all! Maybe someone have a circuit for bandpass filter. My interesting frequency is from 10KHz to 13.5KHz

Try this
see if that helps

LOL!!

Yes off coarse I will test all schematics from google till find one who will work. I just need working bandpass schematic

RC bandpass filters are tried and true, you won't have to try all the schematics, you just need to calculate the values to use based on your needs and build one...

No need to be sarcastic.

A Google search delivers a lot of bandpass circuits. Of course, because there is a schematic for (almost) every purpose. You'll have to find out which one suits your requirements.

You didn't give any information about your requirements and limits. As there are for example (to name only a few):
- bandwidth / frequency range (an audio bandpass is constructed differently than an rf-bandpass)
- signal levels
- operating voltages
- characteristic (bessel, butterworth, chebyshev, elliptic etc...)
- roll-off and stop band attenuation
- any limitations as to used circuit components

etc. etc.

Need from 6 - 7.5kHz or 10-13kHz. It needs to check car gasoline detonation for Audi 20v turbo motors. I think the input signal will by pulse signal from 0 - 12 V

Download this program . Enter your filter parameters. The program will show you the resulting schematic including all required component values.

Can it's possible to build this tipe of filter on arduino base? The signal come from knock sensor ->
