The notion of boundedness, almostperiodicity, asymptotically almost
periodicity, exponential dichotomy, regularity, permissibility, etc. play
very important role in the Qualitative Theory of Linear Differential
Equations. The current exposition is in this direction and is devoted
to the problem of boundedness, almostperiodicity and asymptotically
almostperiodicity of the solutions of linear differential equations with
generalized perturbations (Distributions). In the last several years the
theory of linear differential equations has seen a boost in research re
sults in this direction by a host of mathematicians. Some classical
work in the theory of impulse system include monographs by A.M.
Samoilenko, N.A. Petrovskii, Halanai and D. Wexler etc. The beat
system in linear case is equivalent to impulse system of the form be
low:
(1) dX/dt = A(t)X + k Skk
It is worth considering the general systems with generalized pertur
bation of the form
