WebMar 17, 2024 · For example, you measure a radio signal with a strength of -10 dB and a noise signal of -50 dB. -10 - (-50) = 40 dB. As I stated earlier, calculating SNR can be involved, as well. So, for complex calculations, you divide the value of the desired signal by the amount of the noise and then take the common logarithm of the result, i.e., log (S ÷ N). WebThe calculation of decibel can be done when power is given as well as when current and voltage are given. When power is given: The most basic form for decibel calculations is given below: N d B = 10 l o g 10 ( P 2 P 1) When the voltage and current are given: N d B = 20 l o g 10 ( V 2 V 1) N d B = 20 l o g 10 ( I 2 I 1)
