  Dynamic conductivity of the one-dimensional ion conductor is investigated at
different values of the interaction constant between particles and the
modulating field. The consideration is based on the hard-core boson lattice
model. Calculations are performed for finite one-dimensional cluster using the
exact diagonalization method. Frequency dependence of the dynamic conductivity
and behaviour of its static component (Drude weight) in the charge-density-wave
(CDW) and superfluid (SF) phases are studied. Frequency dispersion of impedance
and loss tangent is calculated; the Nyquist diagrams are built and analyzed.
