A cikin bututu mai tsayi, VSWR da aka auna, ana iya samun kayan shayar sautin tunani da ƙimar ƙima.

A cikin sadarwar rediyo, rashin daidaituwar impedance eriya tare da mai ciyarwa ko eriya mai watsawa rashin daidaituwa, babban ƙarfin kuzari zai haifar da naɗe-haɗe, kuma ɓangaren gaba na tsangwamar igiyar ruwa yana faruwa ga juna. Don siffa da auna halayen VSWR na tsarin eriya, wato, eriya na igiyar gaba da raƙuman haske shine, ya kafa manufar "SWR",

SWR = R / r = (1 + K) / (1-K)

Ƙimar tunani K = (Rr) / (R + r)

(K shine mummunan darajar yana nuna cewa kishiyar lokaci)

Inda R da r ke da tasirin fitarwa da kuma abin shigar da shi. Lokacin da biyu dabi'u kamar yadda impedance, cewa shi ne daidai matches , da tunani coefficient K daidai yake da 0, VSWR ne 1.
