I want to use CAT5e cable for transmitting signals of around 6MHz.
What is the correct resistor value for termination?

100 ohms.

Have Fun!

Hummm... a resistor has V = I*R, while a capacitor has V = integral I*C
dt. So a flux capacitor has Phi on one side or the other.

Now, a reluctance has MMF = Phi * scriptR (a "flux resistor"), so a flux
capacitor should have MMF = integral Phi*C dt.

Now, in flux, it turns out that reluctance is conservative, so its phase
shift should be unconservative (i.e., lossy). In other words, the
imaginary component of permeability mu'', or epsilon'' for permittivity.

Interestingly, this means there is no such thing as a flux inductor
(barring active devices with an external power source), because it would
have negative loss, i.e. instead of consuming power, it would generate
power, like the fabled negative resistor.

In conclusion: a flux capacitor is just a hunk of steel (lots of eddy and
hysteresis loss). ;-)

plus or minus...?

Plus or minus 5% should be fine, depending on what kind of VSWR your
ezuipment is capable of handling. ;-)

Cheers!

Plus. Minus 100R would probably cause oscillation.


;-)

Or as Elmer would say "Wefwections... Huhuhuhuhuhuhu..."

It won't work. CAT 5e has too many tpi. :) Need to step back to
something older.

(wonder how long it will take folks to get what that refers to)

Of course - you've reminded me where I've put that Tunnel Diode.
