Query: The function space to describe the dynamics of linear systems   Usually, the dynamics of linear time-invariant systems described by an
integral operator of convolution type, which is defined in the Hilbert space of
Lebesgue square integrable functions on the whole line. Such a description
leads to contradictions. It is shown that the transition to the Hilbert space
of almost periodic functions leads to the elimination of the detected
inconsistencies. Multiple signals and interference with discrete spectrum are
systems of sets. The properties of these systems lead to a new more effective
method to combat noise in this space. The method used to identify the
differential equations for the airbus. Baseline data were obtained during
automatic landing.
