TīmeklisSNR = signal power/noise power (SNR is a ratio of signal power to noise power) SNR (in dB) = 10*log (signal power / noise power) [base 10] For instance, the SNR for a given communication system is 3dB. So, SNR (in ratio) = 10^ {SNR (in dB) / 10} Therefore, in this instance, the signal power is twice as powerful as the noise power.
