Creation and Annihilation of Trajectories in Discrete-Time Piecewise Constant Systems
Hisato Fujisaka, Takeshi Kamio, Kazuhisa Haeiwa (Hiroshima City Univ.)
Abstract (in Japanese) (See Japanese page) 
(in English) Switched-capacitor sigma-delta modulators possessing quantizers are considered as discrete-time systems with piecewise constant functions.
Trajectories of the systems in a phase space contain distinctive finite-length trajectories reflecting the level of system inputs.
We computed frequency of appearing the finite-length trajectories for the second and third-order systems.
The computation revealed the creation and annihilation of the trajectories depending on system inputs.
Especially for the second-order system, we realized the mechanism of the creation-annihilation phenomenon.
