Under certain constraints, the signal to quantization noise ratio (SQNR) is modeled as (4.33)SQNR≈6.02q where q is the number of bits used. This is, however, not always a good approximation depending on the input signal statistics. More exact conditions for when the quantization noise is ...

This produces a quantizing error in the restored, reconverted analog signal; this error is known as quantizing noise. As shown in Fig. 23, the quantizing error can not exceed ±Q/2. The theoretical maximum peak-to-peak signal-to-quantization-noise ratio (SNR), or dynamic range, of the ...
snrsignalnoiseratiosinad均方根 理论上,一个ADC的SNR(信号与噪声的比值)等于(6.02N+1.76)dB,这里N等于ADC的 位数。虽然我的数学技巧有点生疏,但我认为任何一个16位转换器的信噪比应该是 98.08dB。但当我查看模数转换器的数据手册时,我看到一些不同的情况。比如,16位的 (逐次逼近型)模数转换器指标的典型值通常...
PURPOSE:To enable measurement of the signal-to-quantization noise ratio for compensating the fluctuation of a measured value, by measuring the signal-to-quantization noise ratios at several points of levels near an input level and by averaging them. CONSTITUTION:In addition to an input level Xo ...
Related to Signal to Noise:Signal to noise ratio sig·nal-to-noise ratio (sĭg′nəl-tə-noiz′) n. 1.The ratio of the power of an electrical, electromagnetic, or optical signal to the power of background noise accompanying the signal. ...
Again, there is no easy way to exclude these terms, so “noise” in the SNR measurement includes everything but the fundamental signal and its harmonics. The signal-to-noise-and-distortion ratio, SINAD, includes THD and noise (THD+N) – it is the ratio of the signa...
AN5537 Application note How to use ADC Oversampling techniques to improve signal-to-noise ratio on STM32 MCUs Introduction All STMicroelectronics microcontrollers embed an ADC (analog-to-digital converter) with a given resolution (number of bits) and sampl...
This bit range gives a theoretical dynamic range of 144 dB (using a simplified formula of 6 dB per bit), but in practical terms, the actual signal-to-noise ratio limits the performance to about 90 dB. Similar dynamic signal power ranges are specified for the A/D converter in the Realtek...
