### ** awọn igbesẹ iyipada **
#### ** 1. Bibẹrẹ pẹlu vswr **:
- ṣe iṣiro γ:

\ Gamma = \ frac {{\ Tex {vspr} - 1} {{\ ọrọ {VsWr} + 1}

- Lo γ Lati wa agbara RL, ati afihan agbara ti o wa nipa lilo awọn agbekalẹ loke.

#### ** 2. Bibẹrẹ pẹlu pipadanu ipadabọ (RL ni DB) **:
- ṣe iṣiro γ:

| \ Gamma | = 10 {- \ ọrọ {RL} / 20}

- Lo γ lati wa vwr, ṣe afihan agbara, ati agbara gbigbe.

#### ** 3. Bibẹrẹ pẹlu ipa-ọna / agbara ti o tan imọlẹ **:
- Fun ** Ṣe afihan agbara ** (\ (p _ _ {\ Ọrọ {Awọn ọrọ {Ronu}}

| \ Gamma | = \ sqrt {\ Flac {P _ {\ Ọrọ f {{ọrọ {Ronu}}}}

- Fun ** Igbẹkẹle agbara ** (\ (p _ _ {\ Ọrọ {Trans} \)):

| \ Gamma | = \ sqrt {1 - \ Flac {P _ {\ ọrọ {Okan {Trans}} {100}}

- Lo γ lati ṣe iṣiro vws cwrr ati RL.
