Abstract. The processes of signal spreading in rings of asynchronous threshold elements are considered. An element can be in an active or passive state: if its potential exceeds a threshold, it is active. A chain is a network of elements N1, ..., Nn, in which the only output Ni is connected to the only input Ni+1. The ring is obtained from the circuit by connecting the output Nn to the input N1. The conditions are given under which the ring, after applying an external signal, turns into a system of two-phase oscillators.
