Dear Members,

Giakas is using the higher frequency included in the 95% of the signal amplitude in order to characterise the frequency content of GRF components (http://www.gaitposture.com/article/S.../abstract?cc=y= ). For a frequency of the fundamental harmonic of 1.43Hz, "95% of the signal amplitude is contained in the first 15 harmonics (20.27 Hz) in the Z, 14 harmonics (18.92 Hz) in the Y and 19 harmonics (25.68 Hz) in the X components" . It is not clear for me how he has calculated those values (20.27; 18.92 and 25.68) . I'll be grateful if someone could help me with an explanation!

Many thanks

Sincerely,

Daniel
