Hi,
I'm trying to separate 3 frequency components from an analog signal. The
original signal is composed by the sum of 3 frequencies (1500, 4000 and
10200 Hz) and some noise. The objective is to separate only those 3
frequencies and evaluate their magnitudes. I thought about lots of ways of
doing it, but couldn't get an effective one.
Any ideas?

Cheers,
 Bruno
