METHOD AND SYSTEM FOR DETERMINING THE AMPLITUDE AND/OR PHASE OF THE OUTPUT SIGNAL FOR A TRANSMISSION BODY DEPENDING UPON THE AMPLITUDE OF THE INPUT SIGNAL |
摘要 |
A system for determining the amplitude and/or the phase of the output signal of a transmission link dependent upon the amplitude of the input signal (AM-AM and/or AM-PM characteristic) impresses a test signal (s(t)) on the transmission link, measures the response signal (e(t)) resulting from the test signal (s(t)) by amplitude and/or phase distortion in the transmission link and determines the amplitude response (le(t)l) of the response signal (e(t)) and/or the phase responses (.PHI.s(t), (.PHI.E(t)) of the test signal (s(t)) and of the response signal (e(t)) dependent upon the amplitude response (¦s(t)¦) of the test signal (s(t)). The system can contain a unit for subordinate procedural control, which is connected to the transmission unit and to the measuring device and determines the AM-AM and/or AM-PM characteristic of the transmission link from the phase and/or amplitude response of the test signal and the response signal. |
