  We consider interaction between the small amplitude travelling waves
("sound") and the shock waves in the transmission line containing both
nonlinear capacitors and nonlinear inductors. We calculate for the "sound" wave
the coefficient of reflection from (the coefficient of transmission through)
the shock wave. These coefficients are expressed in terms of the wave speeds
and the wave impedances. When only the capacitors or only the inductors are
nonlinear, the coefficients are expressed in terms of the wave speeds only. We
explicitly include into consideration of the shocks the dissipation,
introducing ohmic resistors shunting the inductors and also in series with the
capacitors. This allows us to describe the shocks as physical objects of finite
width and study their profiles. In some particular cases the profiles were
obtained in terms of elementary functions.
