No distortion lines

Lecture





The line in which the condition is met

  No distortion lines

and the attenuation coefficient does not depend on the frequency and at the same time has a minimum value, is called a line without distortion.

Characteristic impedance does not depend on frequency

  No distortion lines

Phase velocity
Does not depend on frequency or at high frequencies

  No distortion lines

Line without distortion at matched load, voltage and current coincide in phase at any point of the line. The energy of the magnetic and electric fields at any given time are equal to each other.

  No distortion lines

Cable lines without special devices are not suitable for transmission of speech, music over long distances.
The lines are suitable for transmission of speech, music over long distances, when the attenuation coefficient does not depend on the frequency or has a small value.
