Ideally, the amplitude of the X input needed to fully switch the output sign is very small, that is, the X-input exhibits a comparator-like behavior. In some cases, where this input may be a logic signal, a simpler X-channel can be used. A highly-linear mixer such as the

Also, I attracts an open set of initial conditions - it attracts all trajectories in the xy-plane. But I is not an attractor because it is not minimal. The stable xed points ( 1;0) are proper subsets of I that also satisfy condi-
