| http://www.w3.org/ns/prov#value | - This value is an integer value lying in the range (0,1, . . . , N???1) where the actual frequency to which k corresponds depends on the sampling frequency F and N using the formula: f ??? ( tone ) F ??? ( sampling ) = k N ( 3 ) Therefore, k = N F ??? ( sampling ) * f ??? ( tone ) ( 4 ) where f(tone) is the frequency to be detected and k is an integer.
