Abstract :
The efficient computational method for the analysis of circuits driven by digitally modulated narrow band signals is introduced. In comparison with classical approach using AM-AM and AM-PM characteristics the proposed method takes into account the dependence on modulation frequency and hence provides more accurate results. In contrast with the transient harmonic balance technique the new method requires much smaller computational efforts. Examples are given to demonstrate the efficiency and accuracy of the method
