Method and System for Determining the Amplitude and/or Phase of the Output Signal of a Transmission Link as a Function of the Amplitude of the Input Signal

摘要

A method and system for determining the amplitude and/or phase of the output signal of a transmission link 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 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)). Only the amplitude characteristic (|e(t)|) and/or phase characteristic (phi_E(t)) of the response signal (e(t)) are measured.
