Reflection and transmission of a small signal wave from a semi-infinite nonlinear transmission line are considered. When a large amplitude pumping wave of a frequency, f_3,is incident upon the nonlinear line having a constant distributed inductance, L_0,per unit length and a distributed nonlinear capacitance per unit length which obeys the simplified law, C=C_0' (1+ην), the propagation constant of the line is affected by the pumpimg wave. And the propagation characteristics of the small signal wave of a frequency, f_1,is affected by the pumping wave. When the frequency f_3 is assumed to be equal to 2f_1,amplification of the small signal wave takes place in the nonlinear line. This paper describes the reflection coefficient and the transmission coefficient by the boundary between the linear line and the nonlinear one. And this paper also shows the results of the experiment.
