Engineering Physics Annotation << Back HOW TO SPEED EXTENSION LONG LINES AFFECTS AT RESISTANCE F.F. MENDE In the article the behavior of line impedance, which is lengthened by mechanical method, is examined. It is shown that this resistance depends on the rate of lengthening line and can acquire negative importance in the case of the decrease of the length of line. It is shown also, that when the line is lengthened with the speed of larger than the signal velocity in it, this line has the input resistance, equal to the input resistance of infi nite line. Key words: long line, linear capacity, linear inductance, line characteristic. Contacts: E-mail: mende_fedor@mail.ru Pp. 03-05.
