Given a sampled signal with a few sharp peeks in the power spectrum,
what is the best method finding, AS ACCURATELY AS POSSIBLE, the 
frequencies?

The approximate frequencies are known. 


Please send answers to peter@jada.se

Thank you

Other 2 good books has been written by: Sir L. MARPLE and 
S.KAY, both published by Mc G.  HILL, this books do present classical
methods like Periodogram and newer like ARMA-methods or MaxEnt-methods.
