We report an experimental and theoretical evaluation of quantization error in continuous-flow IRMS (CF-IRMS). CO 2 samples (100 pmol–30 nmol) were injected into a gas chromatography combustion IRMS system (GC–CIRMS). The analog signal was digitized by high precision, 24-bit ADC boards at ...
The limiting factor in the resolution of an ADC is quantization noise (quantization error). Assuming that the quantization error is random it can be treated as white noise. The quantization noise power and RMS quantization voltage for an ADC is given by the equation: [4]erms2=q212orerms=...
The signal-to-noise ratio (SNR) of an ADC is the ratio of the signal power to the non-signal power. Non-signal power includes thermal noise, quantization noise, and other residual errors in the converter, measured in the Nyquist bandwidth (fSAMPLE/2) of the ADC. SNR is typically defined...

For ADC, the distances between the sub-vector of the query and the sub-codewords in a subspace are pre- computed on-line and stored in a 1-by-k lookup table. The distance in the original space is simply the sum of the distances computed from the M subspaces. 2.2.3 Iterative ...

Other coding schemes will appear when discussing the implementation of complex converters, e.g., locally ternary (three-level) coding can be used in full differential implementations. In error correction schemes a base lower than 2 is applied. ...

However, when the absolute amplitude of the analog signal exceeds the peak voltage1 Vx,FS/2 of the ADC, the quantization error could become larger than half the quantization step and signal clipping occurs. The step size or resolution of the ADC can be further defined in terms of the ADC ...
