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 continuous equivalent sound level (See definition) is generally calculated on an hourly basis and is shown in the equation as L. WebIntroduction. The dynamic performance of an analog-to-digital converter (ADC) is determined by the effective number of bits (ENOB). In this application note, we examine the relationship of ENOB with other dynamic characteristics of ADCs such as signal-to-noise ratio (SNR), signal-to-noise and distortion ratio (SINAD), and total harmonic distortion …

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.
