Explanation:
SNR is a calculated value that represents the ratio of RMS signal to RMS noise.
One can then multiply the log 10 of this ratio by 20 to derive SNR in decibels. As mentioned above, an ADC's ideal SNR equals 6.02N+1.76 dB
where N is the number of bits.
SNR is defined as the ratio of signal power to the noise power, often expressed in decibels.
A ratio higher than 1:1 which is greater than 0 dB indicates more signal than noise.
