Frequency properties of the non-homogeneous periodical line are analyzed. The model of the signal path containing the non-homogeneous periodical line is presented. The programs for calculation of line input impedance and transfer coefficient were developed. Calculation results are presented and analyzed. They show that the stop–band appears due to periodical inhomogeneities. Its central frequency depends on the length of the period of the line. The width of the stop–band and the attenuation in it depend on intensities of periodical inhomogeneities.
