#26718 - RE: 8051 frequency detection (Address) |
There was a post some time ago on detecting DTMF tones by software. In one of the replies the Goertzel algorithm was mentioned. Of course this is a DSP solution and requires a digitised signal. The response time will be favorable compared to a frequency counter approach, though.
Best regards, Rob Klein. |
