The errors in calculation of normalized impedance
Keywords:
impedance, normalized resistance, calculation errors, standing wave ratioAbstract
This article deals with the problem of errors in calculation of normalized impedance because of the inaccuracy in measuring voltage standing wave ratio VSWR, wave length λ and displacement of minimum electrical field strength along the line dmin in using the slot line. The derived expressions and diagrams give the possibility to determine the limits of use of recalculating the errors of some parametrs (ΔVSWR, Δλ, Δdmin) in the errors of other (ΔR/R, ΔX/X) ones.References
