Which of the following parameter cannot be calculated from the standing waves?(a) Peak voltage and peak current(b) SWR(c) Reflection and transmission coefficients(d) Attenuation constantThe question was posed to me during a job interview.This is a very interesting question from Waveguide Current and Excitation topic in portion Waveguides of Electromagnetic Theory

Answer»

Right choice is (d) Attenuation constant

Easiest explanation: The peak voltage and current can be DIRECTLY measured from the standing WAVES. The standing wave ratio, reflection coefficient and the TRANSMISSION coefficient can also be calculated from it. Only the attenuation constant cannot be calculated directly.
