'''Signal-to-noise and distortion ratio''' ('''SINADR'''<ref>{{cite journal | title=Evaluation of signal-to-noise and distortion ratio degradation in nonlinear systems | journal= IEEE Transactions on Microwave Theory and Techniques|date=March 2004 | volume=52 | issue=3 | pages=813–822 | doi=10.1109/TMTT.2004.823543 | issn=0018-9480| last1=Lavrador | first1=P.M. | last2=Borgesdecarvalho | first2=N. | last3=Pedro | first3=J.C. | bibcode=2004ITMTT..52..813L }}</ref>) is a measurement of the purity of a signal. SINADR is typically used in data converter specifications. SINADR is defined as:
:<math>
\mathrm{SINADR} = \frac{P_\mathrm{signal}}{P_\mathrm{quantizationError} + P_\mathrm{randomNoise} + P_\mathrm{distortion}}
</math>
where <math>P</math> is the average power of the signal, quantization error, random [[Engineering:Noise (electronics)|noise]] and [[Physics:Distortion|distortion]] components. SINADR is usually expressed in [[Physics:Decibel|dB]]. SINADR is a standard metric for [[Analog-to-digital converter|analog-to-digital converter]] and [[Digital-to-analog converter|digital-to-analog converter]].

SINADR (in dB) is related to ENOB by the following equation:
:<math>
\mathrm{SINADR} = ENOB\cdot 6.02 + 1.76
</math>
