    Operateur TFRI                           Voir aussi : TFR
    --------------   
    EVOL2 = TFRI  EVOL1 ;


    Description :
    _____________

    The TFRI operator constructs inverse Fourier transform
 for a signal (opposite of fast Fourier transform).

    Contents :
    __________

    EVOL1  : complex object on which the inverse Fourier
             transform will be performed (EVOLUTION type).
             The step of the abscissae must be constant.
             The EVOLUTION object must be complex :

                 PREE,PIMA  : real part, imaginary part
             or  MODU,PHAS  : modulus, phase


    EVOL2  : real object containing inverse FOURIER transform
             (EVOLUTION type)
