Local noise in, remote signal out! 20 continuously stirred tank reactors (CSTR), all tuned near the Hopf bifurcation, are one‐way coupled together. When the first one is subjected to external parameter noise, oscillation is induced which propagates along the chain with considerable amplification and noise suppression. As a consequence, a rather regular signal is observed at the end of the chain (see picture).
