Calculations for Noise Reduction
Calculating the signal -to -noise ratio (SNR) helps asses the qualty of sensor signal. Te SNR is given by:
Pertama, FLT: 0 = 33; SNR = 20 * log 1; FLT: 1 Ambitude: 1; 10 1; 10; FLT: 2: 3; (Signal amplitudu / Noie Ampitudu) 1; FI1; FLT: 3 3333333D;;
For example, if the signul amplithee is 5V and the noise ampltude is 0.1V, then:
FLT: 0 = 30 = 30 = 20 * log 1; FLT: 1; 10 = 333T; 2: 3 = 20; FL133332323323323232332332332323232323231lt; 33332323232321323213133321.
SNR yang agung mengindikasikan sebuah cleaner signul with with with less noise interference. Am for amn SNR above 30 dB for reliable sensor operation.
