Abstract
The envelope of a signal is broadly defined as the slow changes in time of
the signal, where as the temporal fine structure (TFS) are the fast changes
in time, i.e. the carrier wave(s) of the signal. The focus of this paper is
on envelope and TFS in multi-channel systems. We discuss the difference
between a linear and a non-linear model of information-extraction from the
envelope, and show that using a non-linear method for information-extraction,
it is possible to obtain almost all information about the originating signal.
This is shown mathematically and numerically for different kinds of systems
providing an increasingly better approximation to the auditory system. A
corollary from these results is that it is not possible to generate a test signal
containing contradictory information in its multi-channel envelope and TFS.
