A NEW DIGITAL SIGNAL PROCESSING METHOD FOR ACCURATE PHASE NOISE MEASUREMENT

Abstract:
The enhancement of a previous digital signal processing method, already proposed by the authors for phase noise measurement, is presented in this paper. The method shows itself particularly suitable for evidencing “close-to-the-carrier” phase-noise, which requires very high frequency resolution. Moreover, its input range results to be much wider than that characterizing the previous method, thus allowing a direct analysis of very high frequency carriers as well. The paper begins with the presentation of the key idea underlying the method; then, it describes in detail the proposed measurement procedure; finally, it points up the results obtained in some experimental tests in order to show the new method perspective.
