could we develop FOURE band pass filters for this as we know the frequency domains that are expected and then count the exact frequency
... the Goertzel algorithm, or Goertzel filters. They are a way to design very narrow-band 2nd order IIR filters easily (only one variable), and are used in applications like DTMF tone recognition. If a '51 can handle that ... well, that's another question. |
