METHOD AND SYSTEM FOR DETERMINING THE AMPLITUDE AND/OR PHASE OF THE OUTPUT SIGNAL FOR A TRANSMISSION BODY DEPENDING ON THE AMPLITUDE OF THE INPUT SIGNAL

摘要

#CMT# #/CMT# The system uses a test signal s(t) applied to the transmission element [14] of the device under test [11] to generate a response signal e(t) indicating the amplitude and phase. This is fed to a measuring system [12] coupled to a cycle controller [13] and is used to improve the signal to noise ratio. #CMT#USE : #/CMT# Mobile phones. #CMT#ADVANTAGE : #/CMT# Improved signal quality. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The figure shows system block diagram. 11 : Test device 12 : Measurement system 13 : Cycle controller 14 : Transmission device.
