Vswr, soo celi luminta (RL), oo ka tarjumaya awoodda, iyo awoodda la isugu gudbiyo

Xiriirka ka dhexeeya saamiga mowduuca taagan ee korantada (VSWR), soo celinta luminta (RL), awoodda ka muuqata, iyo awoodda la isugu gudbiyo ayaa iskuxiran is-dhexgalka milicsiga (γ). Hoos waxaa ku yaal qaaciidooyinka furaha ah iyo tillaabooyinka lagu beddelayo:

### ** Qaacida xudunta **
1. ** Milicsiga milicsiga (γ) **:

\ GAMMA = \ FRAC {\ qoraalka {vasr} - 1} {\ qoraal {vast {vast} + 1}

2. ** Vswr ** LO γ:

\ qoraalka {vsswr} = \ frac {1 + | \ Gamma | {1 - | Gadamma |

3. ** Soo celi luminta (RL) ** ee DB:

\ qoraalka {rl (db)} =20 \ log_ {10} (| \ Gada |)

4. ** Awoodda ka muuqata (%) **:

P _ {\ qoraalka {\}} = | \ gamma | ^ 2 \ jeer 100 \%

5. ** Awoodda la isugu gudbiyo (%) **:

P _ {\ qoraalka {grosigay {grosigay {{bidix (1 - | gadagaarka | ^ 2 \ midig) \ jeer 100 \

### ** tillaabooyinka beddelka **
#### ** 1. Laga bilaabo Vswr **:
- Xisaabi γ:

\ GAMMA = \ FRAC {\ qoraalka {vasr} - 1} {\ qoraal {vast {vast} + 1}

- U adeegso γ in la helo RL, oo ​​muujinaya awoodda, iyo awoodda la isugu gudbiyo adoo adeegsanaya qaaciida kor ku xusan.

#### ** 2. Laga bilaabo luminta soo celinta (RL ee DB) **:
- Xisaabi γ:

| \ Gada | = 10 ^ {- \ qoraalka {rl} / 20}

- U isticmaal γ si aad u hesho Vswr, oo muujinaya awood, iyo awood la isugu gudbiyo.

#### ** 3. Laga bilaabo awood ka muuqata / la kala qaado **:
- for **} awood ka muuqda ** (\ (p _ ~ qoraalka {\} \)):

| \ Gada | = \ sqrt {\ fc frec {p _ _ \ {\ qoraalka}} {} {} {}

- ** Awoodda la isugu gudbiyo ** (\ (p _ {\ qoraalka {geddi}):

| \ Gada | = \ sqrt {1 - \ frac {p _ _ \ {\ qoraalka {} {100}}}

- U isticmaal γ in la xisaabiyo Vswr iyo RL.

### ** Miiska Tusaalaha **
| ** vswr ** | ** Soo laabashada Guuldarada (DB) ** | ** Awoodda ka tarjumaysa (%) ** | ** Awoodda la isugu gudbiyo (%) ** |
|----- |
| 1.0 | ∞ (ciyaar fiican) | 0% | 100% |
| 1.5 | 14.0 dB | 4% | 96% |
| 2.0 | 9.5 dB | 11.1% | 88.9% |
| 3.0 | 6.0 dB | 25% | 75% |

### ** qoraalada furaha **
- a ** vswr of 1: 1 ** macnaheedu ma aha wax milicsan (γ = 0, rl = ∞).
- ** Valswr sare ** ama ** hoose RL ** wuxuu muujinayaa awood badan oo ka tarjumaya.
- ** Awoodda la isugu gudbiyo ** waa la kordhiyaa marka Vswr ≈ 1.

U adeegso qaaciidooyinkan si ay u indha-indheeyaan inta u dhexeysa cabirrada caqabad ku habboon ee ku habboon nidaamyada RF.
