How Do Transmission Lines Function as Parallel LC Circuits?

[wakko101]

I'm currently doing a lab on pulses in cables. The instructions describe the transmission line as a series of parallel lc circuits that transmit the pulse back and forth along the line, but I'm not sure I understand exactly how it works. I understand how an individual lc circuit works, but I'm unsure about how they are acting together in the transmission line.

Can anyone provide some insight into this?

Cheers,
W. =)

Have you learned about the "Telegrapher's Equations" yet? Here's a link -- your text should have these equations as well:

(note: the wikipedia.org site is not necessarily accurate or stable, especially on more complex technical and Physics-related topics. On this EE topic, it's pretty reliable and stable, especially if you follow the links in it to verify and further your understanding.)
