Abstract :
This note discusses a technique for representing linear bandpass systems in terms of a state-variable formulation (first-order matrix differential equation) involving complex-valued envelope functions. In narrow-band cases this yields a model involving more slowly varying quantities, and thus, less computing time is required for a given simulation task.
