This calculator allows you to convert the signal/noise and distortion ratio (SINAD) expressed in decibels (dB) into the effective number of bits (ENOB). It is commonly used to evaluate the quality and performance of analog-to-digital converters (ADCs), indicating their actual accuracy.
Formula
ENOB = (SINAD − 1.76) / 6.02
Explanation of the formula
SINAD represents the overall quality of a signal, including noise and distortions. By applying this equation, we obtain the number of effective bits (ENOB), which reflects the equivalent resolution of the ADC. The higher the SINAD, the larger the ENOB, which means more faithful signal conversion.
Uses of the calculator
- Evaluation of the performance and precision of ADC converters.
- Analysis of signal quality in digital systems.
- Comparison of different analog-to-digital conversion circuits.
- Practical tool for electronic engineers and RF system designers.
