Abstract
An initial configuration of the filter cellular automaton introduced by Park, Steiglitz, and Thurston can be thought of as consisting of a number of particles. Here we present a complete analysis of the evolution of single particles. In particular, conditions are given for the existence of periodic particles, and the period is computed in terms of the initial data.
