A method and system for determining the amplitude and/or phase of the output signal of a transmission link (14) according to the amplitude of the input signal (AM-AM and AM-PM characteristics). The response signal (e(t)) emanating from a test signal as a result of amplitudes and/or phase distortion in the transmission link (14) is determined with respect to the associated amplitude characteristics (|e(t)|) and/or associated phase characteristics (.phi.E(t)) according to the test signal (s(t)). According to the invention, only the amplitude characteristic (|e(t)|) and/or phase characteristic (.phi.E(t)) of the response signal (e(t)) are measured.
L'invention concerne un procédé et un système pour déterminer l'amplitude et/ou la phase du signal de sortie d'un chaînon de voie de transmission (14) en fonction de l'amplitude du signal d'entrée (caractéristiques AM-AM et AM-PM). Le signal de réponse (e(t)) provenant d'un signal d'essai (s(t)) par l'intermédiaire d'amplitudes et/ou d'une distorsion de phase dans le chaînon de voie de transmission (14) est déterminé en fonction du signal d'essai (s(t)) relativement aux courbes d'amplitude correspondantes (|e(t)|) et/ou aux courbes de phase correspondantes (f8(t). Selon l'invention, seules la courbe d'amplitude (|e(t)|) et/ou la courbe de phase (f8(t) du signal de réponse (e(t)) sont mesurées.
