I have an application where I need to find the lowest frequencyDigital filtering, of course.
component in an audio signal
(say 500Hz..8KHz) comprised of a number of unrelated tones. This will
not necessarily be the dominant amplitude component and I will need to
have an amplitude threshold below which minor components are ignored.
DSP based solutions are not ideal. Something analog and low powered
would be ideal. Suggestions ?.
