Thats not what he meant, imo. Yes, the lengh of the line effects the
results, however, the claim is that whatever the line length, it
*always* acts like a transmission line, such that you can always use the
transmission line formulars, rather then a capacitor.
This is/was actually a bit of a "controversy", brought to the media in
strong terms in Wireless World about 25 years ago by Ivor Catt on this
matter. i.e. a capacitor is a transmission line. All good stuff for
SuperSpice, a very affordable Mixed-Mode
Windows Simulator with Schematic Capture,
Waveform Display, FFT's and Filter Design.
