what is VSWR?
Answer / md ahmeduddin farooqi
In telecommunications, standing wave ratio (SWR) is the
ratio of the amplitude of a partial standing wave at an
antinode (maximum) to the amplitude at an adjacent node
(minimum), in an electrical transmission line.
The SWR is usually defined as a voltage ratio called the
VSWR, for voltage standing wave ratio
