METHOD FOR MEASURING OF TIME DELAY IN ENVELOPE ELIMINATION AND RESTORATION LINEAR TRANSMITTER, AND APPARATUS THEREOF

摘要

PURPOSE: A time delay measuring method of an encoding linearization transmitter is provided to compare a time delay according to a path of a phase signal and an amplitude signal of an input signal in order to measure time delay of an input signal and an output signal of an encoding linearization transmitter. CONSTITUTION: A time delay measurement unit distributes a pulse-modulated sine wave signal into different transmission lines(110). The time delay measurement unit extracts an amplitude modulation signal and a phase modulation signal from the modulated sine wave signal(130). The time delay measurement unit detects an envelope of the amplitude modulation signal.
