WebThe DNL resolution is 1/ (Number of samples per code). So, if you want to know your DNL to 0.1 LSB accuracy, you need 10 samples per code. So if you have a 12-bit ADC, you need 10*2^10 = 10,240 samples minimum. Usually you probably want more like 0.01 LSB accuracy so you would need 102,400 samples. WebDay-Night Average Sound Level (DNL, L dn) A rating of community noise exposure to all sources of sound that differentiates between daytime and nighttime noise exposure. The equation for it is.

"The DNL is usually measured in LSb, although we can measure it as an absolute value (either volts or amperes) or as a percentage of the full-scale value. Integral Non-Linearity (INL) The INL is defined as the maximum deviation of the actual input-output characteristic from the ideal transfer characteristic.

I've saved the data (including the ... WebAlthough the inherent differential nonlinearity (DNL) of the ADC will cause deviations from an ideal Gaussian distribution (for instance, some DNL is evident in Figure 2), it should be at least approximately Gaussian. If there is significant DNL, the value of σ should be calculated for several different dc input voltages and the results averaged.

Differential nonlinearity (acronym DNL) is a commonly used measure of performance in digital-to-analog (DAC) and analog-to-digital (ADC) converters.
