R – internal (output) impedance of the signal source.
BH
R – balancing resistor on the signal source side.
The cable must be paired (shielded twisted pairs) with wave resistance of wire pairs Zw.
Below is a practical case where a broadband operational amplifier acts as a remote voltage source
(providing a low-impedance voltage output in the frequency band up to 10 MHz).
