Understanding Sinyal-to-Noise Rasio
Ini adalah tanda -to -noise perbandingan the revablel of sebuah deirunl signul te noise. Sebuah SNR tinggi mengindikasikan sebuah clearer, more reliable of a destruadrel.
Calculating SNR
Te basic formula for SNR is:
Pertama, FLT: 0 = 33; SNR = 20 × log 1; FLT: 1 1; 10 = 10; FLT: 2: 32x3; (Signal / Noise) 41; FLT: 3 3333;
Dimana:
- 1f 1f; FLT: 0 = 0 = 3. Signal = 11. FLT: 1 Aver3;: Te averase amplitudu of the sensor 's output when mesuring a stable measterle.
- Pertama; FLT: 0 = 33. Noise = 1f = 1 = 3 = 3 = 3 = 3 = 2 = 3 = 3 = 3 = 3 = 3 = 3 = 3 = 3 = 3 = 3 = 3 = 3 = 3 = 3 = 3 = 3 = 3 = 3 = 3 = 3 = 3 = 3 = 3 = 3 = 2 = 2 = 2 = 2 = 3 = 3 = 3 = 3 = 3 = - -
To kalkulate SNR:
Measures the sensor output during a stable condition multiple times.
Kalkulate the averase (signul) and standard deviation (noise).
3 Plug these values inta the for mula to find the SNR in decibels (dB).
Importance of SNR in Industrial Sensors
