SINAD to ENOB converter
This page of converters and calculators section covers SINAD to ENOB converter and ENOB to SINAD converter.
EXAMPLE:
INPUT: SINAD in dB = 20.00
OUTPUT: ENOB in bits = 3.02
ENOB to SINAD converter
EXAMPLE:
INPUT: ENOB = 3.0 bits
OUTPUT: SINAD = 19.82 dB
Effective Number of Bits-ENOB
It defines measured performance of ADC with reference to input frequency. As input frequency will increase overall noise also will increase. Hence it will reduce ENOB and also SINAD. The relation of ENOB with SINAD is expressed as follows.
SIgnal to Noise And Distortion ratio-SINAD
The ratio of sine wave rms signal frequency input to ADC with rms value of (noise+ harmonic) content.
It is expressed in dB.
SINAD = 20*log10 ( SIGNALrms / (NOISE+HARMONICS)rms ) ;
SINAD vs ENOB Equation
Following equation or formula is used to convert from SINAD to ENOB and viceversa.
