The main principles of the formation
of nonsteady state responses of physical systems to the pulse excitation (free
induction decay and echo signals) and their common features, which permit
to use them in information processing, are discussed in the review. Specific
examples of the systems and of some important phenomena in this field are
listed. The restrictions of the processors based on nonsteady state responses
and possible ways to improve their efficiency are discussed.
