Method for decomposing an anharmonic periodic signal and corresponding computer program

Abstract

This method for decomposing an anharmonic periodic signal, the general form of which may be expressed as x(t)=x0+x1 cos(Φ(t)), wherein Φ(t) is the phase of the signal, is characterized in that it consists of: determining an expression of the phase equation F  ( Φ ) =  Φ  t , determining an expression of the phase Φ(t) as a function of de parameters (r, rk, Φ1, pk) measuring the anharmonicity of the signal and its morphology, from p cosn and p sinn functions defined by: p   cos n  ( t , r ) = ∑ k = 1 ∞  cos  ( kt )  r k k n   and   p   sin n  ( t , r ) = ∑ k = 1 ∞  sin  ( kt )  r k k n .
