TIME-FREQUENCY METHODS FOR TRANSMITTER MEASUREMENTS

J. Cichocki, D. Grabowski, S. Maszczyk

Abstract

Digital Signal Processing techniques allow for significant simplification of measurement arrangements and decrease measurement time during tests of radiocommunication transmitters. The paper deals with usage of time-frequency transformations for evaluation of frequency and modulation properties of FM transmitters. The method based on Short-Time Fourier Transform (STFT) has been proposed and discussed taking into account results of simulations and experiments.
