5 What Are Lines And Stanzas? Line A line is pretty self-explanatory. Line A line of a poem is when it jumps Line To a new, well, line, Line Like this! Line Sometimes a line is a complete sentence. Line But it doesn’t Line Have to be! Line A stanza is kind of like a paragraph. Line Stanzas are made up of lines. Line This “stanza” has five lines.

SPICE has two transmission-line components: T, the lossless transmission-line component; and O, the lossy transmission-line component. The lossless line simulates only delay and characteristic impedance. For the lossy line; you must enter the primary line parameters, but at this time it is

The transmission line has a low-pass characteristic because of the dielectric loss and the skin effect loss. That is, the higher-frequency component is more severely attenuated by transmission line than the lower frequency component. This phenomenon is modeled by a lossy transmission line model (W model) in
