Describe VSWR?..

Answer / sunil choudhary

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.

 Is This Answer Correct ? 37 Yes 7 No

Describe VSWR?..

Answer / prashant mathur

VSWR stands Voltage Standing Wave Ratio. It means ratio of
output voltage Vo to the input voltage Vin.

VSWR = Vo/Vin

 Is This Answer Correct ? 20 Yes 7 No

Describe VSWR?..

Answer / roshan singh

When a transmission line (cable) is terminated by an impedance that does not match the characteristic
impedance of the transmission line, not all of the power is absorbed by the termination. Part of the power
is reflected back down the transmission line. The forward (or incident) signal mixes with the reverse (or
reflected) signal to cause a voltage standing wave pattern on the transmission line. The ratio of the
maximum to minimum voltage is known as VSWR, or Voltage Standing Wave Ratio.
