I think Filipe gave enough info.

If this is student project then it is unfair to ask for any full spec.

I don't agree. He has been asking e.g. for the required ADC resolution. The question can rarely be anwered from the given information. I would also guess, that a spectral analysis of the input signal is intended, unfortunately it hasn't been said clearly. Just copying the project title would most likely clarify a lot.
At the present state, the appropriate general suggestion is: Start with a digital signal processing text book, e.g. Stearns/Hush.
