S. Ben-yaakov et al., Envelope simulation by SPICE-compatible models of electric circuits drivenby modulated signals, IEEE IND E, 47(1), 2000, pp. 222-225
SPICE-compatible equivalent circuits were developed to facilitate the analy
sis and envelope simulation of electric circuits driven by modulated signal
s, The circuits are based on a novel complex phasor domain transformation.
The proposed method facilitates fast simulation of any general linear circu
it driven by a modulated signal, such as amplitude, frequency, or phase mod
ulation.
