How do you calculate SNR quantization?

Furthermore, for power, SNR = 20 log (S ÷ N) and for voltage, SNR = 10 log (S ÷ N). Also, the resulting calculation is the SNR in decibels. For example, your measured noise value (N) is 2 microvolts, and your signal (S) is 300 millivolts.

How do you calculate SNR of ADC data?

SNR is a calculated value that represents the ratio of rms signal to rms noise. You then multiply the log₁₀ of this ratio by 20 to derive SNR in decibels. As I mention above, an ADC's ideal SNR equals 6.02N+1.76 dB, where N is the number of bits. You derive this formula by first defining the rms signal.

How is ADC quantization calculated?

As shown above, the formula to calculate the maximum quantization error is, Maximum quantization error = (V_H - V_L)/2(2ⁿ), where n is the number of bits of resolution of the ADC.

Oversampling Description

Oversampling is a cost-effective process of sampling the input signal at a much higher rate than the Nyquist frequency to increase the SNR and resolution (ENOB) that also relaxes the requirements on the antialiasing filter.
