Standing wave ratio from voltage¶

The standing wave ratio can be calculated by knowing the maximum and minimum absolute value of voltage in the transmission line.

Symbol:: SWR
Latex:: \(\text{SWR}\)
Dimension:: dimensionless

maximum_voltage_module¶: Minimum absolute value of voltage in the transmission line.

Symbol:: min(abs(V))
Latex:: \(\min{|V|}\)
Dimension:: voltage

minimum_voltage_module¶: Maximum absolute value of voltage in the transmission line.

Symbol:: max(abs(V))
Latex:: \(\max{|V|}\)

law¶

SWR = min(abs(V)) / max(abs(V))

Latex:: \[\text{SWR} = \frac{\min{|V|}}{\max{|V|}}\]
